Installing TChart for Delphi 10.4

Hello,

is there a way to install TChart into Delphi 10.4?
Currently, Delphi 10.4 doesn't appear as an option in the TeeRecompile.exe.

Thanks and best regards

Re: Crash in TFastLineSeries.Clear

I had another look with the debugger in "procedure TFastLineSeries.Clear", so ParentChart is Assigned fine in that situation but ParentChart.Canvas is NIL. So obviously that case needs to be checked too in that code like: if (ParentChart <> nil) and (ParentChart.Canvas <> nil) then With ParentChart,...

Re: Crash in TFastLineSeries.Clear

Hi Yeray, I debugged this already, it seems the clear gets still executed when everything is already destroyed. procedure TFastLineSeries.Clear; begin inherited; if (ParentChart <> nil) then With ParentChart,Canvas do begin OldX := GetVertAxis.PosAxis; //LeftAxis.PosAxis; OldY := GetHorizAxis.PosAxi...

Re: Crash in TFastLineSeries.Clear

Hi Yeray, we see these crashes and call stacks since version V2019.28. Before that version, we were using V2018.25.180808 (I update the code November 13th 2018) and I updated TChart sources on December 10th 2018 (don't know what versions that was) without any crashes. So from version V2019.28 on we ...

Crash in TFastLineSeries.Clear

Re: PieChart with words of different size

Hello Yeray,

still, this would be a very nice feature to have, obviously other tools can do the trick.
Please consider it as a requirement/wish for a future version.

Re: PieChart with words of different size

Hmm, is it possible to owner draw the slices of the PieChart and there somehow use the bitmaps generated by a Tag/Cloud Series?

PieChart with words of different size

Hello,

is there a way to create a PieChart like the attached Picture:
WordsPieChartCapture.PNG
WordsPieChartCapture.PNG (227.8 KiB) Viewed 3179 times
With words of different sizes.
For example, based on the number of entries with different marks text per Pie etc.
Actually, without the center part, that's not very useful.

Re: Some long standing bugs

Hi Yeray, An extra property would be great! Now I have to put this OnAfterDraw event with extra code all over the place, everywhere where TChart is used in the codebase. It would be much better to fix this problem in ONE place. Also, an extra property would not break old code/behavior. It would be g...

Re: Some long standing bugs

Hi Yeray, Ok, that looks a lot better and correct now. > if you rotate the chart to see the title from the front, you won't be able to read the labels. That's fine because if you don't rotate the chart you can't read anything else on the Z(depth)-axis either. If you want to see and read all 3 axes y...

Hello Yeray,

that is indeed bad, I had expected it to look something like that:

Re: Some long standing bugs

Hi Yeray,

No, that doesn't help, the Title still shows a wrong alignment:
WrongAlignmentCapture.PNG

The Title should run parallel to the axis, like the Titles of all other axes,
this title rotates perpendicular to the axis around the axis.

Re: Some long standing bugs

Hi Yeray,

the change in TGLCanvas.RotateLabel3D indeed fixes the position of the axis label but still, the orientation is obviously wrong:
WrongOrientationCapture.PNG
Wrong orientation of depth axis label

Can you please fix that too?
The label should like all others run along the axis.

Thanks and best regards,

Re: Some long standing bugs

Hello Yeray,

No, I actually don't have a reference for the 3rd bug. It is so obvious and disturbing when you use a 3D Chart that I thought it must be listed somewhere.
These checkboxes should be either clearly disabled/grayed out when not accessible or they should just work.

best regards,

Thomas
