Hello,
could you please share me the code you're using ? or just tell me which series types you're drawing ?
I've been trying to reproduce the problem by usign some series types and all worked fine.
Maybe it's happenning at the time to draw something on canvas ?

Thanks

After much research, the problem is caused by the use of your BannerTool.

I was dynamically creating a BannerTool in the ViewModel's InitializingChartControl() which is called in my constructor of the View.

If I comment out the creation and references to it, the application runs fine.

Sample creation code:
_BannerTool = new BannerTool(Chart);

_BannerTool.Shape.Color = System.Drawing.Color.Transparent;
_BannerTool.Shape.Font.Color = System.Drawing.Color.LightGray;
_BannerTool.Shape.Font.Size = 15;
_BannerTool.Shape.Shadow.Visible = false;
_BannerTool.Shape.Pen.Visible = false;
_BannerTool.Position = AnnotationPositions.Center;
_BannerTool.TextAlign = Steema.TeeChart.Drawing.StringAlignment.Center;
_BannerTool.Text = "";

Hope this help you!

Hello,
it's strange, because I've just checked and it's working fine here by using a BannerTool.
Please, can you check if the attached sample demo that uses the code you sent to me, is working fine to you ?
