How to set different Label in Legend in Pie Chart

c#, mschart, pie-chart, winforms

Solution

Yes, this is easily done by setting the `LegendText` for each of your `DataPoints` like this:

foreach (DataPoint dp in yourSeries.Points) dp.LegendText = yourLabel;

If your x-values contain meaningful numbers you can use them:

foreach (DataPoint dp in s.Points) dp.LegendText = dp.XValue + "";

But if you added the x-values as strings they are lost and you have to use another source for the `LegendTexts`.

If you only have a fixed number of `DataPoints` you can set the `LegendTexts` directly:

yourSeries.Points[0].LegendText = "hi";
yourSeries.Points[1].LegendText = "ho";
yourSeries.Points[2].LegendText = "hum";

Note that usually a `Legend` shows one entry per `Series`. But for a `Pie` chart it shows one entry per `DataPoint`!
