Description christopher ireland 2016-12-15 07:27:45 EST 
At the moment we can do:

  public class MyAnnotation : Annotation
  {
    public MyAnnotation(Chart c) : base(c) { }

    protected override void DrawString(Graphics3D g, int x, int y, int t, int tmpHeight, string[] s)
    {
      g.TextOut(x, y + (t - 1) * tmpHeight, 0, s[t - 1], Shape.TextFormat == TextFormat.Html);
    }
  }

And then:

    private void InitializeChart()
    {
      MyAnnotation tool = new MyAnnotation(tChart1.Chart);
      tool.Shape.TextFormat = TextFormat.Html;
      tool.Shape.Font.Size = 20;
      tool.Text = "<b>Hello</b>" + Texts.LineSeparator + "<i>World</i>";
    }

However, Annotatioin.AutoSize does not work under all circumstances for the size of the text. This request to incorporate these changes in the Annotation tool and to better its sizing with Html text.
