Color line is very slow

Hello,
There is simple example in attachment, which adds two color lines to the chart.
The color line that was added first can be smoothly moved, however color line that was added second moves very-very slowly. Also, at this time cursor flickers.
Please suggest what can I do to make them all move smoothly.
Thanks.

I'm afraid I can't reproduce this issue here with the latest publicly available version of TeeChart.dll. Here is a video of the behaviour on my machine:

which version of TeeChart.dll are you using? Are you using a modern video card?

Have you tried downloading the latest evaluation version from here:
http://steema.com/download/net
to see if that resolves the issue?

Latest version works fine.
Support, is there a workaround for version 3.5?
Thanks.

No, I'm afraid there isn't.

I was able to fix the issue, but I do not understand why does this work. I have found an old project with color lines, which all move smoothly and step by step removed its parts until it stop working.
It is not clear why, but it works because of Steema.TeeChart.Tools.Annotation object placed on my UserControl. You can find it in the project with the name "annotationMaxLabel".
Also, the annotation configured in a very strange manner:
Code: Select all
this.annotationMaxLabel.Shape.Shadow.Visible = true;
this.annotationMaxLabel.Shape.Top = -100;
this.annotationMaxLabel.Shape.Transparent = true;
this.annotationMaxLabel.Top = -100;
Please find example in attachment.
