Hi Manal,
What do you mean by different legend - by default all series in a chart display on the legend the chart is attached to. You can have series from different chart displaying on different legend - please check the following example:
All Examples \ Panels \ Legends \ Series Assignment

Let us know if you have any questions or meet any problems.

Hi Team,

Is it possible to have single legend for multiple series. Currently when I add 2 series to 1 chart I end up having different legends for both the series. But I want to have the same legend for both the series.

Thanks and regards
Manal
