Hello Sivam,

You can set a marker by using the PointMark property of the chart series. Here is a sample code:

mySeries.Appearance.PointMark.Visible = true;
mySeries.Appearance.PointMark.FillStyle.FillType = Telerik.Reporting.Charting.Styles.FillType.Solid
mySeries.Appearance.PointMark.FillStyle.MainColor = System.Drawing.Color.Red

All the best,
Steve

Hi Sivam,

If you manually set the series color, then you can control this process easily by applying the same color to the PointMark as to the series.
However if you depend on the auto assigned series colors, you cannot do this out of the box. Still here are the colors that the auto generated series use, so you can use them for your PointMarks if you want:

1st: Color.FromArgb(213, 247, 255)
2nd: Color.FromArgb(218, 254, 122)
3rd: Color.FromArgb(136, 221, 246)
4th: Color.FromArgb(163, 222, 78)
5th: Color.FromArgb(79, 152, 198)
6th: Color.FromArgb(86, 153, 78)

Generally they are ComplexGradient from 3 colors, but in your case, only the first color of this gradient would do.

Sincerely yours,
Steve
