Thumbnail of TChart

Hi, I am wondering whether TChart has a feature to display a thumbnail (small copy) of the main (large) chart? The small one should reflect the changes of the large one.
Thanks.

In which environment are you working? Windows forms, WPF, ASP.NET?

You could try something like this:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      tChart1.Series.Add(typeof(Bar)).FillSampleValues();
    }


    private void button4_Click(object sender, EventArgs e)
    {
      Form thumbForm = new Form();

      thumbForm.Size = new Size(200, 200);
      thumbForm.Show(this);

      TChart thumbChart = new TChart();
      thumbChart.Dock = DockStyle.Fill;
      thumbForm.Controls.Add(thumbChart);

      MemoryStream stream = new MemoryStream();
      tChart1.Export.Template.Save(stream);
      stream.Position = 0;
      thumbChart.Import.Template.Load(stream);
    }
