Hi Tracey
You're passing a constant string expression ('any old string') to GetAxisLabel() which expects a variable.
Try this var AxisLabel : String; begin GetAxisLabel(LeftAxis, HorizBarSeries, 1,AxisLabel); ShowMessage('The label axis is ' + AxisLabel); end;
Todd.

Subject: [DUG]: TChart Set LeftAxis Labels
Hi
I have dynamically created a Chart, with 3 HorizBarSeries which are mbStacked.
What I now need to figure out is how to set the Left Axis labels to display the contents of another field returned by my query for that record.
does anyone know how to do this without affecting the data values?
The closest i have come to success so far is:
procedure GetAxisLabel(Sender: TChartAxis; Series: TChartSeries; ValueIndex: Integer; var LabelText: string); begin if Sender = FChart.LeftAxis then if ValueIndex < 1 then LabelText := '' else LabelText := IBQuery1.FieldByName('system').AsString; end;
WebActionWhatever; begin stuff GetAxisLabel(LeftAxis, HorizBarSeries, 1, 'any old string'); end;
But I keep getting a compile error : constant object cannot be passed as a var parameter.
Anyone here know how to acheive this??
