Hello crb,

I can reproduce your problem and I have added your request in bug list report with number[TF02016003]. We will try to fix it for next maintenance releases of TeeChart.Net.

Hello crb,

I inform you that the bug of number [TF02016003] will not be resolved, because this issue is a problem in Direct2D. To avoid the problem I recommend use colorline drag, please set DragRepaint to true as do in next lines of code:

Code: Select all

ColorLine tool = new ColorLine(tChart1.Chart);
tool.Axis = tChart1.Axes.Bottom;
tool.AllowDrag = true;
tool.Value = 3;
tool.DragRepaint = true; 

Thanks,
