Hi,

Also if you resize the chart smaller, so that the left and right axis touch, theres an access violation.

I've decided not to disable the DrawAllPoints since it's more trouble than it's worth.

Hi, I've found a problem with TFastLineSeries( A ) that uses another TFastLineSeries( source ) as a DataSource. If A has DrawAllPoints set to false and source has less than 2 points then an access violation is thrown everytime the chart is drawn. I've included a small sample project with this setup....

Hi Narcís, The two screen-shots are actual shots of the chart. The only modifications I made was to crop the form. The first screen-shot is while I'm holding the left mouse button down just before releasing it, the rectangle is the zoom rectangle drawn by teechart. The second is just after releasing...

Hi, Found a fix for my main project. For the OnScroll and OnZoom events I set the cursor series axis to automatic. Chart1.LeftAxis.Automatic:= true; This can be used, in my case, since the axis for the cursor is never shown. But I guess in the cases where it is not this would still be an issue. Kjaran

Hi, I have now updated to the "TeeChart Pro v2011.04.41118 32bit VCL" and indeed my original problem has been solved, many thanks. :) And still using "Delphi XE with Update 1, 15.0.3953.35171".

I ended up by calling it in the TChart.OnMouseEnter.

But I can see that it could fail if there are some non mouse events that change the form position or size.

Calling Repaint on the cursor fixes the problem.

But I'm not sure when to call it.

If I put it in the Cursor.OnChange the CPU use goes up to 10% when scrolling instead of 0-2%.
In the Form.OnPaint it is good for MDI but if the TChart goes off screen the paint event doesn't trigger.

Hi, I have a problem with the cursor not working correctly after moving a form outside the screen (or mainform for MDI) and back. The cursor will be visibly stuck but it is possible to move it around. If you minimize the form and restore it the cursor has moved and is working again. But as soon as y...
