Hi Team,

Is there any way to set specific image or icon(jpeg, png, etc..) as a MarkerStyle for DataPoints ?

Hi Changmin,

Yes you can assign an image to a marker using the NImageFillStyle - for example:
   NPointSeries point = new NPointSeries();
    point.Size = new NLength(0);
    point.DataLabelStyle.Visible = false;
    point.MarkerStyle.Visible = true;
    point.MarkerStyle.FillStyle = new NImageFillStyle("c:\\temp\\markerimage.png");
    point.Values.Add(10);
    chart.Series.Add(point);
We hope this helps - let us know if you have any questions.

Your answer helped me a lot.

I have one more question.
How can I rotate the DataPoint(NPolarDataPoint) (pin : center of the point) ?

Hi Changmin,
Can you please elaborate on this question - we're not sure what exactly you need to accomplish...

I want to make specific PolarDataPoint which is pinned at the center of it rotate.
Thanks.

Hi Changmin,
Unfortunately there is no way to apply a transformation on the marker, however you can use custom painting to draw markers - please take a look at the following example:

All Examples \ Custom Painting
The examples show how to perform custom painting on the chart. 

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