You can use the image itself in an ImagePoint series, or draw it directly onto the canvas, e.g.
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
ImagePoint point = new ImagePoint(tChart1.Chart);
point.PointImage = Image.FromFile(@"C:\tmp\1.png");
point.Pointer.HorizSize = 30;
point.Pointer.VertSize = 20;
point.FillSampleValues();
tChart1.AfterDraw += tChart1_AfterDraw;
}
void tChart1_AfterDraw(object sender, Graphics3D g)
{
g.Draw(Utils.FromLTRB(10, 10, 70, 50), Image.FromFile(@"C:\tmp\1.png"), true);
}
Is that what you meant?

I'm not sure what the problem is here. The following code works as expected, with the series title being correctly displayed in the legend:
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
ImagePoint point = new ImagePoint(tChart1.Chart);
point.PointImage = Image.FromFile(@"D:\tmp\1.png");
point.Pointer.HorizSize = 30;
point.Pointer.VertSize = 20;
point.FillSampleValues();
point.Title = "My Point";
tChart1.Legend.LegendStyle = LegendStyles.Series;
}

Hello amol,
ImagePoint is the specific series style, which is derived from Points series, to plot images as pointers. If you don't want to use ImagePoint series you can achieve almost the same creating your own custom series, deriving it from Points series and overriding its drawing methods as in the example I posted here:
