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;
    }

I'm sorry, I'm afraid I don't understand your request. Could you please provide some code to show me what you need?

You have taken ImagePoint point = new ImagePoint(tChart1.Chart) in your example but i have taken Point ps=new Point(). i want to achieve same functionality using Point how can i achieve this?

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: http://www.teechart.net/support/viewtopic.php?t=4309
