I have set the following code but the function never gets called, is there an alternative?
Chart1.OnGetAxisLabel := Chart1GetAxisLabel;

Hello,
As soon as there's a series with data in the chart, it should be called. Could you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Apologies for the late reply (was away for 2 weeks). I tried it out in a smaller program and the event-handler is called, hence must be a problem in my code.
Thanks for all the help.

Hello,
Sorry, I forgot to mention the OnGetAxisLabel isn't fired for an axis when you set it with custom labels. In this case you already control what texts are drawn and at what positions so you shouldn't need the event.

For the text being shown in a shape, is there a way to wrap it in case it doesn't fit into a rectangle?

Hello,
Instead of formatting the texts with
sLineBreak as I do at
GetText function, you could use
wraptext function once the chart has been drawn. Ie, at the end of your
FormCreate:
Code: Select all
procedure TForm1.FormCreate(Sender: TObject);
var textW, shapeW: Integer;
begin
//...
Chart1.Draw;
for i:=0 to Chart1.SeriesCount-1 do
with Chart1[i] as TChartShape do
begin
Chart1.Canvas.AssignFont3D(Font);
textW:=Chart1.Canvas.TextWidth(Text.Text);
shapeW:=Bounds.Right-Bounds.Left;
if textW>shapeW then
begin
charW:=Chart1.Canvas.TextWidth('W');
Text.Text:=WrapText(Text.Text, shapeW div charW);
end;
end;
Chart1.Draw;
end;
