Index: Number;
The Index property determines index of the chart data series.
Use JSON or the setIndex method to set the property value and the getIndex method to get the property value.
The setIndex method contains the value parameter that sets index of chart data series, and the redraw parameter that indicates whether chart needs to be redrawn.
Available values for the redraw parameter:
true. The chart should be redrawn (default).
false. Chart rerendering is not required.
The example of use is given on the Example of Creating a Pie Chart page.
