Is There any way of creating a Subchart that is a descendant of TDBChart rather Than TChart as we Have a lot of specialised Code that Requires a TDBChart

The subChart.addchart appears to only return a TChart
I would Like a TDBChart result
any sugestions greatly appreciated

regards

Hello,

I've created a TDBChart at runtime assigning the main Chart as Parent and redrawing it at the parent's OnAfterDraw event as done with the SubChartTool, and it seems to work fine:

UnfortunatelY get Compile Error for Project

Noticed tis error with another example

Compiler goes to Here

Procedure TTeeCanvas.TextOut(const X,Y:TCoordinate; const Text:String; AllowHtml:Boolean);
begin
if AllowHtml then
HtmlTextOut(Self,{$IFDEF FMX}Round{$ENDIF}(X),{$IFDEF FMX}Round{$ENDIF}(Y),Text)
else
TextOut(X,Y,Text);
end;

Hello,

Please check the paths and the prefix.
- Paths: Using the source code version, you could use references to the sources in the "Library Path":
$(TeeChartInstall)\Source\VCL;$(TeeChartInstall)\Source\FMX;

Note "TeeChartInstall" is an "Environment Variable" pointing to the TeeChart installation, by default: "C:\Program Files (x86)\Steema Software\Steema TeeChart Pro VCL FMX Source Code 2018.24"

- Prefixes: Since XE4, you should add "VCLTee" prefix to the "unit scope names" in VCL projects and "FMXTee" prefix in FMX projects.
