I tried this:

series.Points.Add(new XYDataPoint(2, 3, "A", false));

series.PEs.Add(new PaintElement(Color.DarkBlue));

ScatterChartAppearance scatterApp = app.ChartTypeAppearance as ScatterChartAppearance;

scatterApp.Character = '*';

scatterApp.CharacterFont = new Font("Tahoma", 28, FontStyle.Regular, GraphicsUnit.Point);

and this works ok.

Could you send us and the rest of your code?

Thanks Taushanov,

 That worked when I upgraded the version to 8.2.

 Now I have a different problem. I was controlling the display of points thru my code. Here it is.

((ScatterChartAppearance)CL1.ChartTypeAppearance).Icon = SymbolIcon.Character;

((ScatterChartAppearance)CL1.ChartTypeAppearance).CharacterFont = new Font("Tahoma", 8, FontStyle.Regular , GraphicsUnit.Point);

But even since I upgraded these settings does not apply. What could be the reason ?

 Now I get the datapoints displayed in Green rather than dark blue as it was prior to the upgrade.

Thanks.
