Chart Attributes

Functional Attributes

You can 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.

These attributes let you control the functional properties of a heat-map chart.

Name Type Range Description
animation Boolean 0/1 This attribute gives you the option to control animation in your charts. 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.
maxLabelHeight
Since 3.5.0
Number In Pixels This attribute can be used to set the maximum height for the x-axis labels (data labels) excluding the x-axis title. If any label goes beyond this height, the label will be truncated. In stagger mode, the number of stagger lines will be reduced if they exceed this value.
maxLabelWidthPercent Numeric In Pixels Restricts the maximum space allotted for the y-axis data labels with respect to the chart's width. If a data label is longer than the specified percentage width then it will either be wrapped or get truncated, subject to the availability of vertical space. Unnecessary space is not reserved for the labels. If all the labels are shorter than the specified maximum width, this value is not applied.
useEllipsesWhenOverflow 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.

Chart Padding & 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
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).

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.
legendPadding Number In Pixels Padding of legend from right or bottom side of canvas
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.

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 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 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 the numbers, set this attribute to 1.
