Chart Attributes

Functional Attributes

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

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.
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, `"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 JSON.
showLabels Boolean 0/1 It sets the configuration whether the x-axis labels will be displayed or not.
labelDisplay String 'AUTO', 'WRAP':, 'STAGGER', 'ROTATE', '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 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.
showYAxisValues Boolean 0/1 The y-axis 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.
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.
showZeroPlaneValue Boolean 0/1 Allows you to show or hide the value of the zero plane.
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.
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'`.
yAxisMinValue Number Numeric Value 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 Numeric Value 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.
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.

Anchors

Anchors (or marker points) are polygons which appear at the joint of two consecutive lines/area points. These are indicators to show the position of data points.

The anchors handle tool tips and links for the data points. So, if you opt to not render anchors on a chart, the tool tips and links won't function. You can, however, hide them by setting their transparency to 0 and still enable tool tips and links. In area charts, anchors are set transparent by default. In case you wish to show the anchor, use anchorAlpha="100" attribute.

These attributes let you configure and customize the anchors on your chart.

Divisional Lines and Grids

Divisional lines are horizontal or vertical lines running through the canvas. Each divisional line signifies a smaller unit of the entire axis, thus aiding the users in interpreting the chart.

The zero plane is a 2D/3D plane that signifies the 0 position on the chart. If there are no negative numbers on the chart, you won't see a visible zero plane.

Alternate color bands are colored blocks between two successive divisional lines.

Number Formatting Properties

FusionCharts XT offers you a lot of options to format your numbers on the chart.

These attributes let you control a myriad of options like:

  • Formatting of commas and decimals
  • Number prefixes and suffixes
  • Decimal places to which the numbers will round to
  • Scaling of numbers based on a user defined scale
  • Custom number input formats

These attributes let you appropriately format the numbers displayed on the chart.

Name Type Range Description
formatNumber Boolean 0/1 This configuration determines whether the numbers displayed on the chart will be formatted using commas, for example, 40,000 if `"formatNumber":"1"` and 40000 if `"formatNumber":"0"`.
formatNumberScale Boolean 0/1 Configuration whether to add K (thousands) and M (millions) to a number after truncating and rounding it - for example, if `formatNumberScale` is set to 1, 1043 would become 1.04K (with decimals set to 2 places). Same with numbers in millions - an M will be added at the end.
defaultNumberScale String The default unit of the numbers that you are providing to the chart.
numberScaleUnit String Unit of each block of the scale.
numberScaleValue String Range of the various blocks that constitute the scale.
scaleRecursively
Since 3.2.1
Boolean 0/1 Whether recursive scaling should be applied.

Number How many recursions to complete during recursive scaling? -1 completes the entire set of recursion.
scaleSeparator
Since 3.2.1
String What character to use to separate the scales that are generated after recursion?
numberPrefix String Character Using this attribute, you could add prefix to all the numbers visible on the graph. For example, to represent all dollars figure on the chart, you could specify this attribute to ' $' to show like $40000, $50000.
numberSuffix String Character Using this attribute, you could add suffix to all the numbers visible on the graph. For example, to represent all figures quantified as per annum on the chart, you could specify this attribute to ' /a' to show like 40000/a, 50000/a.
decimalSeparator String Character This attribute helps you specify the character to be used as the decimal separator in a number.
thousandSeparator String Character This attribute helps you specify the character to be used as the thousands separator in a number.
thousandSeparatorPosition
Since 3.2.1
Number   This option helps you specify the position of the thousand separator.
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.
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.
decimals Number 0-10 Number of decimal places to which all numbers on the chart would be rounded to.
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 be automatically converted to 23.40 (note the extra 0 at the end).
forceYAxisValueDecimals
Since 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.
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.

Data Plot Hover Effects

If you wish to show an effect on the data plot (column, line anchor, pie etc.) when the user hovers his mouse over it, you can apply the hover effects to a data plot.

These attributes let you configure the hover effect for all data plots in the chart.

Name Type Range Description

Chart Paddings and Margins

PowerCharts XT allows you to 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 will 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.

These attributes let you configure the functional and cosmetic properties of chart paddings and margins.

Name Type Range Description
canvasPadding Number In Pixels Lets you set the space between the canvas border and first & last data points
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.
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 at 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, PowerCharts XT 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.

The <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 will appear on the chart.

For a single-series spline area chart, a typical <set> element will look like:

<set label='January' value='17400' />

These attributes let you configure individual data values in a data-set.

Name Type Range Description
label String This attribute determines the label for the data item. The label appears on the x-axis of chart.
value Number Numerical value for the data item. This value would be plotted on the chart.
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 data item 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.
showLabel Boolean 0/1 You can individually opt to show or hide labels of individual data items using this attribute.
showValue Boolean 0/1 You can individually opt to show or hide values of individual data items using this attribute.
valuePosition
Since 3.2
String "ABOVE", "BELOW", "AUTO" If you have opted to show a particular data value on the chart, this attribute lets you adjust the vertical alignment of individual data values with respect to dataplots. By default, this attribute is set to AUTO mode in which the alignment of a data value is determined automatically based on the position of its plot point. In ABOVE mode, a data value is displayed above the plot point unless a plot point is too close to the upper edge of the canvas while in BELOW mode, a data value is displayed below the plot point unless a plot point is too close to the lower edge of the canvas.
anchorSides Number 3 or more If you want to configure data item specific anchor properties, this attribute lets you define the number of sides for the anchor of that particular data item.
anchorRadius Number In Pixels If you want to configure data item specific anchor properties, this attribute lets you define the radius for the anchor of that particular data item.
anchorBorderColor Color Hex Code If you want to configure data item specific anchor properties, this attribute lets you set the border color for the anchor of that particular data item.
anchorBorderThickness Number In Pixels If you want to configure data item specific anchor properties, this attribute lets you set the border thickness for the anchor of that particular data item.
anchorBgColor Color Hex Code If you want to configure data item specific anchor properties, this attribute lets you set the background color for the anchor of that particular data item.
anchorAlpha Number 0-100 If you want to configure data item specific anchor properties, this attribute lets you set the alpha for the anchor of that particular data item.
anchorBgAlpha Number 0-100 If you want to configure data item specific anchor properties, this attribute lets you set the background alpha for the anchor of that particular data item.

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.

Use the code snippet shown below to render a vertical trend-line on the chart:

    "data": [{
        ...
    },
    {
        "linePosition": "0.8",
        "vLine": "true"
    },
    ...

These attributes let you configure the functional and cosmetic properties for vertical trend-lines and trend-zones.

Name Type Range Description
color Color Hex Code 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.

Trend-lines

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

Trend-lines are horizontal 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.

Use the code snippet shown below to render a horizontal trend-line on the chart:

    ...
    "chart": {
                ...
        };

    "trendlines": [{
          "line": [{
              "startvalue": "177500",
              "color": "#00cc00",
              "displayvalue": "Target"
         }]
    }]

    ...

These attributes let you customize the functional and cosmetic properties for trend-lines.

Name Type Range Description
startValue Number Numeric Value The starting value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `startValue` would be 102.
endValue Number Numeric Value The ending y-axis value for the trendline. Say, if you want to plot a slanted trendline 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 do not 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 will be displayed as a line or a zone (fill-colored rectangle).
showOnTop Boolean 0/1 Whether the trend line or trend 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 trend zone.
