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 configure the functional and cosmetic properties of tool-tips.

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.

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.

The <category> Element

Each <category> element represents a pie slice.

These attributes let you configure the functional and cosmetic properties for the pie slices.
