 <chart> element Attributes
Functional Attributes

These attributes let you control a variety of functional elements on the chart. For example, you can opt to show or hide data labels, data values, y-axis values. You can also set chart limits and extended properties.

Attribute Name Type Range Description
base Number Positive Numeric Value apart from 1 Using this attribute, you can set the base of the logarithmic chart. The value has to be a positive numeric value apart from 1.
invertYAxis Boolean 0/1 Whether to use inverted y-axis so that y-axis upper limit appears at canvas bottom instead of top.
animation Boolean 0/1 This attribute lets you set the configuration whether the chart should appear in an animated fashion. If you do not want to animate any part of the chart, set this as 0.
palette Number 1-5 Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme. Valid values are 1-5.
paletteColors String List of hex color codes separated by comma While the palette attribute allows to select a palette theme that applies to chart background, canvas, font and tool-tips, it does not change the colors of data items (that is, column, line, pie etc.). Using paletteColors attribute, you can specify your custom list of hex colors for the data items. The list of colors have to be separated by comma. For example,
<chart paletteColors='FF0000,0372AB,FF5904...'>.
The chart will cycle through the list of specified colors and then render the data plot accordingly.

To use the same set of colors throughout all your charts in a web application, you can store the list of palette colors in your application globally and then provide the same in each chart XML.
showAboutMenuItem Boolean 0/1 Setting this to 1 shows up a custom context menu in the chart, which can be customized to show your text and can be linked to your URL. For example, you can set the context menu of the chart to include "About your company name" and then link to your company home page. By default, the chart shows "About FusionCharts" when right clicked.
aboutMenuItemLabel String   The menu item label for the custom context menu item.
aboutMenuItemLink String URL Link for the custom context menu item. You can specify the link in FusionCharts Link Format to be able to open the same in new window, pop-ups, frames or as JavaScript links.
showLabels Boolean 0/1 It sets the configuration whether the x-axis labels will be displayed or not.
labelDisplay String AUTO              Since v 3.2
WRAP
STAGGER
ROTATE or
NONE
Using this attribute, you can customize the alignment of data labels (x-axis labels). There are 5 options: AUTO, WRAP, STAGGER, ROTATE or NONE. By default, this attribute is set to AUTO mode which means that the alignment of the data labels is determined automatically depending on the size of the chart. WRAP wraps the label text if it is too long to fit in one line. ROTATE rotates the labels vertically. STAGGER divides the labels into multiple lines.
useEllipsesWhenOverflow
Since v 3.2
Boolean 0/1 When enabled in AUTO mode, long data labels are truncated by adding ellipses to prevent them from overflowing the chart background. The default value is 1.
rotateLabels Boolean 0/1 This attribute lets you set whether the data labels would show up as rotated labels on the chart.
slantLabels Boolean 0/1 If you have opted to show rotated labels on chart, this attribute lets you set the configuration whether the labels would show as slanted labels or fully vertical ones.
labelStep Number 1 or above By default, all the labels are displayed on the chart. However, if you have a set of streaming data (like name of months or days of week), you can opt to show every n-th label for better clarity. This attributes just lets you do so. It allows to display every n(th) x-axis label.
staggerLines Number 2 or above If you have opted for STAGGER mode as labelDisplay, using this attribute you can control how many lines to stagger the label to. By default, all labels are displayed in a single line.
showValues Boolean 0/1 Sets the configuration whether data values would be displayed along with the data plot on chart.
rotateValues Boolean 0/1 If you have opted to show data values, you can rotate them using this attribute.
placeValuesInside Boolean 0/1 If you have opted to show data values, you can show them inside the columns using this attribute. By default, the data values show outside the column.
showShadow Boolean 0/1 Whether to show shadows for data plot.
rotateYAxisName Boolean 0/1 If you do not wish to rotate y-axis name, set this as 0. It specifically comes to use when you have special characters (UTF8) in your y-axis name that do not show up in rotated mode.
yAxisNameWidth Number (In Pixels) If you opt to not rotate y-axis name, you can choose a maximum width that will be applied to y-axis name.
clickURL String The entire chart can now act as a hotspot. Use this URL to define the hotspot link for the chart. The link can be specified in FusionCharts Link Format.
defaultAnimation Boolean 0/1 By default, each chart animates some of its elements. If you wish to switch off the default animation patterns, you can set this attribute to 0. It can be particularly useful when you want to define your own animation patterns using Styles feature.
showZeroPlaneValue Boolean 0/1 Allows you to show or hide the value of the zero plane.
showPrintMenuItem Boolean 0/1 When you write click on the chart it shows a context menu. This attribute allows you to show or hide the "Print" option in the context menu.
showTooltipforWrappedLabels Boolean 0/1 When the labels of the chart are too lengthy, the chart truncates them and displays a part of the label. In this situation, this attribute shows a tooltip displaying the complete label when the mouse is hovered on the shortened labels.
unescapeLinks Boolean 0/1 Internally the chart decodes a Url that you set as link. Before invoking the link it again encodes the Url. If you are passing multilingual characters via a Url or do not want this decode-encode mechanism to be handled by chart you can set,unescapeLinks='0'.
showLimits Boolean 0/1 Whether to show chart limit values. If not specified showYAxisValues overrides this value.
showDivLineValues Boolean 0/1 Whether to show div line values. If not specified showYAxisValues overrides this value.
showYAxisValues Boolean 0/1 The y-axis of the charts is divided into vertical sections using div (divisional) lines. Each div line assumes a value based on its position. Using this attribute you can set whether to show those div line (y-axis) values or not. The values of showLimits and showDivLineValues if specified explicitly overrides the value of this attribute.
yAxisMinValue Number This attribute helps you explicitly set the lower limit of the chart. If you do not specify this value, it is automatically calculated by the chart based on the data provided by you.
yAxisMaxValue Number This attribute helps you explicitly set the upper limit of the chart. If you do not specify this value, it is automatically calculated by the chart based on the data provided by you.
centerYaxisName
Since v 3.2.1
Boolean 0/1 This attribute when set to '1', allows you to align the y-axis name with respect to the height of the chart. When set to '0', the y-axis name is aligned with respect to the height of the canvas.

Data Plot Cosmetics

These attributes let you configure how your plot (columns, lines, area, pie or any data that you are plotting) would appear on the chart.

If the plots can show borders, you can control the border properties using the attributes listed below. Or, if they support gradient fills, you can again configure various properties of the gradient using these attributes.

Various other controls over plot cosmetics can be attained using this set of attributes.

thousandSeparatorPosition
Since v 3.2.1
Number   This option helps you specify the position of the thousand separator. For more details, please see Advanced Charting > Number Formatting > Basics page.
inDecimalSeparator String Character In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, the chart accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the decimal separator. For more details, please see Advanced Charting > Number Formatting section.
inThousandSeparator String Character In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, the chart accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the thousand separator. For more details, please see Advanced Charting > Number Formatting section.
decimals Number 0-10 Number of decimal places to which all numbers on the chart would be rounded to. For more details, please see Advanced Charting > Number Formatting section.
forceDecimals Boolean 0-1 Whether to add 0 padding at the end of decimal numbers. For example, if you set decimals as 2 and a number is 23.4. If forceDecimals is set to 1, the number will automatically be converted to 23.40 (note the extra 0 at the end). For more details, please see Advanced Charting > Number Formatting section.
yAxisValueDecimals Number 0-10 If you have opted to not adjust div lines, you can specify the div line values decimal precision using this attribute. For more details, please see Advanced Charting > Number Formatting section.
forceYAxisValueDecimals
Since v 3.2
Boolean 0/1 Whether to forcefully attach decimal places to all y-axis values. For example, If you limit the maximum number of decimal digits to 2, a number like 55.345 will be rounded to 55.34. This does not mean that all y-axis numbers will be displayed with a fixed number of decimal places. For instance 55 will not be displayed as 55.00 and 55.1 will not become 55.10. In order to have fixed number of decimal places attached to all y-axis numbers, set this attribute to 1. For more details, please see Advanced Charting > Number Formatting section.

Font Properties

Using the attributes below, you can define the generic font properties for all the text on the chart. These attributes allow you a high level control over font properties.

If you intend to specify font properties for individual chart elements (like Caption, sub-caption etc.), you'll need to use the Styles feature of PowerCharts XT. Using Styles, you can also specify advanced font properties like Bold, Italics, HTML Mode etc.

Attribute Name Type Range Description
baseFont String Font Name This attribute lets you set the font face (family) of all the text (data labels, values etc.) on chart. If you specify outCnvBaseFont attribute also, then this attribute controls only the font face of text within the chart canvas bounds.
baseFontSize Number 0-72 This attribute sets the base font size of the chart, that is, all the values and the names in the chart which lie on the canvas will be displayed using the font size provided here.
baseFontColor Color This attribute sets the base font color of the chart, that is, all the values and the names in the chart which lie on the canvas will be displayed using the font color provided here.
outCnvBaseFont String Font Name This attribute sets the base font family of the chart font which lies outside the canvas, that is, all the values and the names in the chart which lie outside the canvas will be displayed using the font name provided here.
outCnvBaseFontSize Number 0-72 This attribute sets the base font size of the chart, that is, all the values and the names in the chart which lie outside the canvas will be displayed using the font size provided here.
outCnvBaseFontColor Color This attribute sets the base font color of the chart, that is, all the values and the names in the chart which lie outside the canvas will be displayed using the font color provided here.

Chart Padding & Margins

The following attributes help you control chart margins and paddings.

PowerCharts XT allows you manually customize the padding of various elements on the chart to allow advanced manipulation and control over chart visualization. Padding in PowerCharts XT is always defined in pixels, unless the attribute itself suggests some other scale (like plotSpacePercent).

You can also define the chart margins. Chart Margins refer to the empty space left on the top, bottom, left and right of the chart. That means, PowerCharts XT would not plot anything in that space.

It's not necessary for you to specify any padding or margin values. PowerCharts XT automatically assumes the best values for the same, if you do not specify the same.

Attribute Name Type Range Description
captionPadding Number In Pixels This attribute lets you control the space (in pixels) between the sub-caption and top of the chart canvas. If the sub-caption is not defined, it controls the space between caption and top of chart canvas. If neither caption, nor sub-caption is defined, this padding does not come into play.
xAxisNamePadding Number In Pixels Using this, you can set the distance between the top end of x-axis title and the bottom end of data labels (or canvas, if data labels are not to be shown).
yAxisNamePadding Number In Pixels Using this, you can set the distance between the right end of y-axis title and the start of y-axis values (or canvas, if the y-axis values are not to be shown).
yAxisValuesPadding Number In Pixels This attribute helps you set the horizontal space between the canvas left edge and the y-axis values or trend line values (on left or right side). This is particularly useful, when you want more space between your canvas and y-axis values.
labelPadding Number In Pixels This attribute sets the vertical space between the labels and canvas bottom edge. If you want more space between the canvas and the x-axis labels, you can use this attribute to control it.
valuePadding Number In Pixels It sets the vertical space between the end of columns and start of value textboxes. This basically helps you control the space you want between your columns or anchors and the value textboxes.
legendPadding Number In Pixels Padding of legend from right or bottom side of canvas
plotSpacePercent Number 0-80 (In Percent) On a column chart, there is spacing defined between two columns. By default, the spacing is set to 20% of canvas width. If you intend to increase or decrease the spacing between columns, you can do so using this attribute. For example, if you wanted all columns to stick to each other without any space in between, you can set plotSpacePercent to 0. Similarly, if you want very thin columns, you can set plotSpacePercent to its max value of 80.
chartLeftMargin Number In Pixels Amount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space.
chartRightMargin Number In Pixels Amount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space.
chartTopMargin Number In Pixels Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space.
chartBottomMargin Number In Pixels Amount of empty space that you want to put on the bottom of your chart. Nothing is rendered in this space.
canvasLeftMargin Number In Pixels This attribute lets you control the space between the start of chart canvas and the start (x) of chart. In case of 2D charts, the canvas is the visible rectangular box.

Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, the chart automatically calculates this space depending on the elements to be placed on the chart. However, if you want to over-ride this value with a higher value, you can use this attribute to specify the same. Please note that you cannot specify a margin lower than what has been calculated by the chart.

This attribute is particularly useful, when you have multiple charts placed in a page and want all their canvas start position to align with each other - so in such a case, you can set same margin value (a value large enough that it does not get rejected by chart owing to it being lower than the calculated value) for all such charts in the page.
canvasRightMargin Number In Pixels Like canvasLeftMargin, this attribute lets you set the space between end of canvas and end of chart.
canvasTopMargin Number In Pixels Like canvasLeftMargin, this attribute lets you set the space between top of canvas and top of chart.
canvasBottomMargin Number In Pixels Like canvasLeftMargin, this attribute lets you set the space between bottom of canvas and bottom of chart.

<categories> element

The <categories> element lets you bunch together x-axis labels of the chart. For a Multi-series chart, it is necessary to provide data labels using <category> elements under <categories> element.

The following properties of <categories> element help you control the font properties of data labels.

Attribute Name Type Range Description
font String Valid font face Lets you specify font face for the x-axis data labels.
fontSize Number Lets you specify font size for the x-axis data labels.
fontColor Color Hex Code Lets you specify font color for the x-axis data labels.
Back to top Back to Top

<category> element

Each <category> element represents an x-axis data label.

In Multi-series charts, it is necessary to provide an equal number of <category> elements and data items (<set> elements within each <dataset>). PowerCharts XT plots only those data items for which it could find a respective <category> element.

You can specify the following attributes for <category> element:

Attribute Name Type Range Description
label String This attribute determines the label for the data item. The label appears on the x-axis of chart.
showLabel Boolean 0/1 You can individually opt to show/hide labels of individual data items using this attribute.
toolText String The tooltip defined in the <category> element appears only when the mouse cursor is hovered over the data plots. However, this will not appear when the cursor is moved over the data labels (except for a situation when long labels are automatically truncated with ellipses. In this situation, if the mouse cursor is hovered over a truncated label, the tooltip will appear with the full label).

In case you want to set a short label and show the full label in tooltip, define the full label using this attribute within the <category> element. The tooltip with the full label will appear only when the mouse is hovered on the dataplot.

Vertical data separator lines

vLines are vertical separator lines that help you separate blocks of data. These lines run through the height of the chart, thereby segregating data into different blocks. In case of bar charts, they are horizontal and run through the width of chart.

For example, if you are plotting a chart showing monthly sales from October 2005-Mar 2006, you might want to plot a vertical separator line between Dec 2005 and January 2006 to indicate end of year.

In logarithmic charts, it is used between <category> elements as under:

<categories>
   <category label='Oct 2005' />
   <category label='Nov 2005' />
   <category label='Dec 2005' />
   <vLine color='FF5904' thickness='2' />
   <category label='Jan 2006' />
   <category label='Feb 2006' />
</categories>

You can configure the cosmetics of vertical separator lines using the following attributes:

Attribute Name Type Range Description
color Color Hex Color This attribute defines the color of vertical separator line.
thickness Number In Pixels Thickness in pixels of the vertical separator line.
alpha Number 0-100 Alpha of the vertical separator line.
dashed Boolean 0/1 Whether the vertical separator line should appear as dashed.
dashLen Number In Pixels If the vertical separator line is to appear as dashed, this attribute defines the length of dash.
dashGap Number In Pixels If the vertical separator line is to appear as dashed, this attribute defines the length of dash gap.
label String   Label for the vertical separator line, if to be shown.
showLabelBorder Boolean 0/1 Whether to show a border around the vLine label.
linePosition Number 0-1 Helps configure the position of vertical line, that is, if a vLine is to be plotted between 2 points Jan and Feb, user can set any position between 0 and 1 to indicate the relative position of vLine between these two points (0 means Jan and 1 means Feb). By default, it is 0.5 to show in between the points.
labelPosition Number 0-1 Helps configure the position of the vLine label by setting a relative position between 0 and 1. In vertical charts, 0 means top of canvas and 1 means bottom. In horizontal charts, 0 means left of canvas and 1 means right.
labelHAlign String left, center, right Horizontal anchor point for the alignment of vLine label.
labelVAlign String top, middle, bottom Vertical anchor point for the alignment of vLine label.
Back to top Back to Top

<dataset> element

Each <dataset> element contains a series of data.

For example, if we are plotting a monthly sales comparison chart for 2 successive years, the first data-set would contain the data for first year and the next one for the second year.

You can provide data-set level cosmetics so that all data within that data-set will be plotted in the same color/alpha/etc.

Also, each data-set can be named using the seriesName attribute of <dataset> element. The series name appears in the legend of the chart. In our previous example, the series name could have well been 2005 and 2006 for first and second data-set respectively.

Depending on the chart type, there are a number of properties which you can define for each <dataset> element.

Attribute Name Type Range Description
seriesName String Lets you specify the series name for a particular data-set. For example, if you are plotting a chart to indicate monthly sales analysis for 2005 and 2006, the seriesName for the first dataset would be 2005 and that of the second would be 2006. The seriesName of a data-set is shown in legend.
color Color Hex Code (Or Comma separated list) This attribute sets the color using which columns, lines, area of that data-set would be drawn. For column chart, you can specify a list of comma separated hex codes to get a gradient plot.
alpha Number 0-100 This attribute sets the alpha (transparency) of the entire data-set.
ratio String Comma separated list of ratios If you have opted to show columns as gradients, this attribute lets you control the ratio of each color. Please see Advanced Charting > Using Gradients to get more information.
showValues Boolean 0/1 Whether to show the values for this data-set.
dashed Boolean 0/1 Whether this data-set would appear as dashed.
includeInLegend Boolean 0/1 Whether to include the seriesName of this data-set in legend. This can be particularly useful when you are using combination charts and you have used the Area or Line chart to plot a trend, and you do not want the seriesName of that trend to appear in legend.
Back to top Back to Top

<set> element

Each <set> element (child of <dataset> element) represents a set of data which is to be plotted on the graph and determines a set of data which would appear on the chart.

For a logarithmic column chart, it could look like:

<dataset seriesName='2006'>
	<set value='35445' />
	<set value='35675' />
	.... and so on ....
</dataset>

In Multi-series charts, you should again note that the number of <category> elements should be equal to the number of data points in each data sets, that is, if you mention twelve categories (twelve months), the data for both years (2005 & 2006) should also contain twelve <set> elements (twelve rows of data).

Attribute Name Type Range Description
value Number Numerical value for the data item. This value would be plotted on the chart.
color Color Hex Code For Multi-series charts, you can define the color of data-sets at dataset level. However, if you wish to highlight a particular data element, you can specify it's color at "set" level using this attribute. This attribute accepts hex color codes without #.
ratio String Comma separated list of ratios If you have opted to show individual columns as gradients, this attribute lets you control the ratio of each color. Please see Advanced Charting > Using Gradients to get more information.
displayValue String   If instead of the numerical value of this data, you wish to display a custom string value, you can specify the same here. Examples are annotation for a data item etc.
link String You can define links for individual data items. That enables the end user to click on data items (columns, lines, bars etc.) and drill down to other pages. To define the link for data items, use the link attribute. You can define links that open in same window, new window, pop-up window or frames. Please see Advanced Charting > Drill Down Charts for more information. Also, you'll need to URL Encode all the special characters (like ? and &) present in the link.
toolText String By default, PowerCharts XT shows the series Name, Category Name and value as tool tip text for that data item. But, if you want to display more information for the data item as tool tip, you can use this attribute to specify the same.
showValue Boolean 0/1 You can individually opt to show or hide values of individual data items using this attribute. This value over-rides the data-set level value.
dashed Boolean 0/1 Whether the border of this data item should appear as dashed. This is particularly useful when you want to highlight a data (such as forecast or trend etc.). This value over-rides the data-set level value.
alpha Number 0-100 For Multi-series charts, you can define the alpha of data-sets at dataset level. However, if you wish to highlight a particular data element, you can specify it's alpha at "set" level using this attribute.
Back to top Back to Top

Trend-lines

Using the <trendLines> element (and children <line> elements), you can define trend lines on the chart.

Trend lines are horizontal or vertical lines spanning the chart canvas which aid in interpretation of data with respect to some pre-determined value. For example, if you are plotting sales data of current year, you might want to add previous year's average monthly sales as trend indicator for ease of comparison.

For each trend line on the chart, you need to define a <line> element under <trendLines> element as under:

<trendLines>
   <line startValue='895' color='FF0000' displayvalue='Average' /> 
</trendLines>

You can control the cosmetic and functional properties of trend-lines using the following attributes:

Attribute Name Type Range Description
startValue Number Numeric Value The starting value for the trend line. Say, if you want to plot a slanted trend line from value 102 to 109, the startValue would be 102.
endValue Number Numeric Value The ending y-axis value for the trend line. Say, if you want to plot a slanted trend line from value 102 to 109, the endValue would be 109. If you do not specify a value for endValue, it would automatically assume the same value as startValue.
displayValue String If you want to display a string caption for the trend line by its side, you can use this attribute. Example: displayValue='Last Month High'.
When you don't supply this attribute, it automatically takes the value of startValue.
color String Hex Code Color of the trend line and its associated text.
isTrendZone Boolean 0/1 Whether the trend would display a line, or a zone (filled colored rectangle).
showOnTop Boolean 0/1 Whether the trend line or zone would be displayed over data plots or behind them.
thickness Number In Pixels If you have opted to show the trend as a line, this attribute lets you define the thickness of trend line.
alpha Number 0-100 Alpha of the trend line.
dashed Boolean 0/1 If you have opted to show the trend as a line, this attribute lets you define whether the trend line would appear as dashed.
dashLen Number In Pixels If you have opted to show trend line as dash, this attribute lets you control the length of each dash.
dashGap Number In Pixels If you have opted to show trend line as dash, this attribute lets you control the length of each dash gap.
valueOnRight Boolean 0/1 Whether to show the trend line value on left side or right side of chart. This is particularly useful when the trend line display values on the chart are colliding with divisional lines values on the chart.
toolText String   Custom tool-text for this trend line or zone.
