Well I found the bug. It is in the following method: Procedure TView3DOptions.SetZoom(const Value:Double); begin if FZoom<>Value then begin if Assigned(FOnChangedZoom) then FOnChangedZoom(Zoom); { <-- offending part! } FZoom:=Value; Repaint; end; end; The parameter given to the handler should not be...

Was there anything changed in the zoom behavior between the releases? Maybe there are new properties to adjust this behavior which I don't know about yet.

Any ideas are much appreciated!

Hello, we upgraded simultaneously from TChart 7 to TChart 8 and from an older Delphi to Delphi 2009. We use the TTree rather extensively and also need the zoom functionality quite often. Now we discovered a change in behavior which is a problem for us. OLD BEHAVIOR (the desired one) : When zooming i...

Thanks again for the fast reply.

Any ideas about when we can expect the next maintenance release ?
And how do I know when you have one uploaded ?

Hi, sorry, again me. in Version 8.04 the ColorgridSeries behaves differently than in Version 7.12: When Setting the SmoothBitmap property to true, in version 7.12 the color between the grid cells was perfectly smoothed, in V8.04 I can see something like a "blurred grid", although this blurred grid i...

As I said in my last post, the pattern image is not the same as the picture for a wall. I think you should also add this new picture property to the chart editor, for the sake of completness.

Sorry Narcis,

here is another one:

TcolorGrid seems not to work with OpenGL Canvas.

Again, TChart 8.04, D2009

Hi Narcis,

how do you mean assigning it via the chart editor?
Do you mean assigning an image to the fill pattern?
If that is the case, this is not the same as assigning to the picture property.

Btw, I think that the Picture property of the walls never made it into the chart editor.

Hi,

When I assign an image to a wall it is not drawn in OpenGL (using TeeOpenGL component). I guess this bug is not related to my other post.

Hi, when I assign a large image (1280 x 1024) to a wall I get an AV. The debugger indicates that the problem is in TeCanvas, Line 3495. Steps to reproduce: Put a Tchart on a Form and a TImage. Load an image into the Timage and assign it to one of the walls: Chart1.BottomWall.Picture.Assign(Image1.Pi...
