 <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
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.
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.
showValues Boolean 0/1 Sets the configuration whether data values would be displayed along with the data plot on chart.
showYAxisValues Boolean 0/1 The y-axis of the chart 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.
showLimits Boolean 0/1 Whether to show chart limit values. If not specified showYAxisValues overrides this attribute.
showDivLineValues Boolean 0/1 Whether to show div line values. If not specified showYAxisValues overrides this attribute.
yAxisValuesStep Number 1 or above By default, all div lines show their values. However, you can opt to display every x(th) div line value using this attribute.
adjustDiv Boolean 0/1 The chart automatically tries to adjust divisional lines and limit values based on the data provided. However, if you want to set your explicit lower and upper limit values and number of divisional lines, first set this attribute to false. That would disable automatic adjustment of divisional lines.
showPrintMenuItem Boolean 0/1 When you right 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'.
showZeroPlaneValue Boolean 0/1 Allows you to show or hide the value of the zero plane.
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.
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.
radarRadius Number In Pixels If you want to explicitly specify a radius for the radar chart, use this attribute. Otherwise, the chart will automatically calculate the best-fit radius.
setAdaptiveYMin Boolean 0/1 This attribute lets you set whether the y-axis lower limit would be 0 (in case of all positive values on chart) or should the y-axis lower limit adapt itself to a different figure based on values provided to the chart.

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.
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.
yAxisValueDecimals Number 0-10 If you've 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.

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 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.

Tool-tip

These attributes let you control the tool tip. You can set the background color, border color, separator character and few other details.

Attribute Name Type Range Description
showToolTip Boolean 0/1 Whether to show tool tip on chart.
toolTipBgColor Color Background Color for tool tip.
toolTipBorderColor Color Border Color for tool tip.
toolTipSepChar String The character specified as the value of this attribute separates the name and value displayed in tool tip.
seriesNameInToolTip Boolean 0/1 For Multi-series charts, PowerCharts XT shows the following information in tool tip (unless tool text is explicitly defined): "Series Name, Category Name, Data Value". This attribute lets you control whether series name would show up in tool tip or not.
showToolTipShadow Boolean 0/1 Whether to show shadow for tool tips on the chart.

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 is not necessary for you to specify any padding/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.
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.
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.
legendPadding Number In Pixels Padding of legend from right or bottom side of canvas

<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.

<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 or 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.

<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 String 0-100 or Comma Separated List This attribute sets the alpha (transparency) of the entire data-set.
showValues Boolean 0/1 Whether to show the values for this data-set.
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.
showPlotBorder Boolean 0/1 Whether to show the border of this data-set.
plotBorderColor Color Color for data plot border of this data-set.
plotBorderThickness Number 0-5 (Pixels) Thickness for data plot border of this data-set.
plotBorderAlpha Number 0-100 Alpha for data plot border of this data-set.
drawAnchors Boolean 0/1 Whether to draw anchors for the particular data-set. If the anchors are not shown, then the tool tip and links won't work for the data-set.
anchorSides Number 3-20 Sets the number of sides that the anchors of the particular data-set will have. For example, an anchor with 3 sides would represent a triangle, with 4 it would be a square and so on.
anchorRadius Number In Pixels This attribute sets the radius (in pixels) of the anchors of the particular data-set. Greater the radius, bigger would be the anchor size.
anchorBorderColor Color Hex Code Lets you set the border color of anchors of the particular data-set.
anchorBorderThickness Number In Pixels Helps you set border thickness of anchors of the particular data-set.
anchorBgColor Color Hex Code Helps you set the background color of anchors of the particular data-set.
anchorAlpha Number 0-100 Helps you set the alpha of entire anchors of the particular data-set. If you need to hide the anchors for the data-set but still enable tool tips, set this as 0.
anchorBgAlpha Number 0-100 Helps you set the alpha of anchor background of the particular data-set.

<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 radar chart, a typical <set> element would look like:

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

In radar 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 its color at "set" level using this attribute. This attribute accepts hex color codes without #.
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.
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.
anchorSides Number 3-20 Lets you specify "set" specific sides of the anchor.
anchorRadius Number In Pixels Lets you specify "set" specific radius (in pixels) of the anchor.
anchorBorderColor Color Hex Code Lets you specify "set" specific border color of the anchor.
anchorBorderThickness Number In Pixels Lets you specify "set" specific border thickness of the anchor.
anchorBgColor Color Hex Code Lets you specify "set" specific background color of the anchor.
anchorAlpha Number 0-100 Lets you specify "set" specific alpha of the anchor.
anchorBgAlpha Number 0-100 Lets you specify "set" specific alpha of the anchor background.
