TeeChart Office

I've been investigating this problem, and I found an interesting thing : actually the axes were note hidden, there were just "cut" because they were at the edge of the chart.

Look the image below to understand : the bottomAxis is "cut" when I'm using a gradient in the TeeSeriesBandTool. For this example, I have changed a bit the axis position to be able to see it.

Can you please check this problem again with v8.02 ? It really seems to be a problem in TeeChart, but I couldn't locate exactly where the axes are cut at the edge of the chart.

I'm using only customAxes (except bottom), maybe it can help you.

P.S. :

Just a tip :
I remember that I had reported a bug about TeeSeriesBandTool :
http://www.teechart.net/support/viewtopic.php?t=6505
Maybe my current problem is linked to the modification you made for this problem.

Hi bertrod,

Thanks for the information but I'm still unable to reproduce the problem here. Could you please send us the *.tee file you are using or a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcìs,

I could not reproduce this problem with a new project.

But I could find exactly what was "cutting" the axes :

In TeeSeriesBandTool.DrawBandTool :

Code: Select all

if Gradient.Visible and ParentChart.CanClip then
begin
  if ParentChart.ClipPoints then
    ParentChart.Canvas.ClipCube(ParentChart.ChartRect,0,ParentChart.Width3D); // <-- this line makes my problem
(...)

The ClipCube cuts the SeriesBandTool, but also my custom and bottomaxes, and I don't understand why.

Do you have a clue ? For exemple, are the axes redrawn after this clip ?

I'm afraid not, we would need to reproduce the issue here to be able to help you on this.

Hi Narcìs,

Just to tell you that I could solve the problem :

I simply added a line

Code: Select all

ParentChart.Canvas.UnclipRectangle()

just after the draw of the gradient.

Dunno why this bug occurs in my project and not on a new project though.
