Hello Ying-Hui,

Unfortunately this is a defect which I have added to our database with id=934. Fortunately there's an easy runtime workaround, which is to derive a new class from Area and override the method which is causing the problem, e.g.

Code: Select all

  public class MyArea : Area
  {
    public MyArea(Chart c) : base(c) { }

    protected override void PrepareLegendCanvas(Graphics3D g, int valueIndex, ref Color backColor, ref ChartBrush aBrush)
    {
       //leave empty
    }
  }

......

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;

      MyArea area = new MyArea(tChart1.Chart);

      area.Add(1, 5, Color.Red);
      area.Add(2, 1, Color.Blue);
      area.Add(3, 4, Color.Yellow);
      area.Add(4, 2, Color.Green);

      area.Stairs = true;
    }
