Hello,

Thanks for the ideas and the code example.
Your tScale class looks interesting.
I've created an issue at bugzilla to discuss about it with the team: #2737

Hello,

The project attached builds and runs for me without errors.

Hello,

I've just double checked it and it seems the IDE version I use here (29.0.51961.7529) is different from yours (29.0.50491.5718).
I'm not sure it will make any difference, but maybe there's an update you can apply.

Hello,

Sorry, but the files were not attached to your message correctly.

Hello Bruce,

I've added it to the public tracker: #2726.

Hello, F2051 Unit VCLTee.Chart was compiled with a different version of System.RTLVersion121 I haven't heard about this one. It sounds as if the VCLTee.Chart.dcu unit found in the library path was build before installing some update or patch in the IDE. I'd try to rebuild the sources, as you did. Te...

Hello Bruce, I'm a bit confused because you keep adding an "L" character between "Geo" and "JSON", while the references I find are without that middle "L". TDataImport class in FMX.Import unit includes an ImportJSON method I believe is unable to load data from that GeoJSON , but I'd like to be sure ...

Hello,

I've added this to the public tracker (#2724).
Thanks for reporting it.

Hello Bruce,

You can manually align two charts playing with margins as in these examples:

viewtopic.php?f=3&t=10620#p44547
viewtopic.php?f=3&t=15313&p=67918#p67918

Hello,

You could detect when the values are jumping from -180 to 180 or vice-versa and add a null point between them.
Or maybe detect when the difference between the value being currently added and the last value exceeds a threshold.

Hello, You could use OnAfterDraw event to manually draw transparent images with StretchDraw method on top of the polygons. Ie: uses Chart, TeeMapSeries, TeePng; var Chart1: TChart; procedure TForm1.FormCreate(Sender: TObject); begin Chart1:=TChart.Create(Self); with Chart1 do begin Parent:=Self; Ali...

Hello, This is when building your project, not at TeeRecompile, isn't it? If so, this happens because the IDE is finding the not prefixed version of the unit (TeCanvas.pas) before finding the prefixed version of the unit (VCLTee.TeCanvas.pas). Does it happen in a new simple project? Check the paths ...

Hello, I'm getting the same problem compiling for win32 in Windows 10 in Delphi 12.1 Patch 1; win32 compilation in Windows 11 works normally. We may be mixing slightly different problems in this thread. Could you please post the exact error message you are getting? I'm not sure it's relevant, but th...

Hello Bruce,

Just to confirm you meant GeoJSON.

Hi,

You can use the ExchangeSeries method with this purpose. For example:
