Hi,

I have a Chart axis added at runtime. Now I fail to assign a series to this axis:

procedure TForm1.TntButton1Click(Sender: TObject);
begin
ca := TChartAxis.Create(Chart1);
ca.Visible := true;
ca.Automatic := true;
ca.Horizontal := true;
ca.PositionPercent := 30;
ca.StartPosition := 20;
ca.EndPosition := 80;
//available Series from designtime
Series1.HorizAxis := THorizAxis(ca);
end;

Is suggest the cast does not work but I saw no alternative while I cannot create a custom THorizAxis at runtime.

Thanks, Messie

Why you don't use

Code: Select all

ca := THorizAxis.Create(Chart1);

?

I think creating a TChartAxis creates a vertical axis, and then you cannot assign it as a horizontal axis.

Because THorizAxis is a type used for settings propertys

type THorizAxis = (aTopAxis, aBottomAxis, aBothHorizAxis, aCustomHorizAxis);

Unit
TeEngine

Description
Type describes Horizontal Axis type.

See also:
TChartSeries.HorizAxis

TChartSeries.HorizAxis is not the same as setting the "Horizontal Axis" in the Chart Editor. I need the way to set the horizontal axis according to the ChartEditor.

Hi Messie,

It seems to me you need to do this

Code: Select all

  Series1.CustomHorizAxis:=ca;

As you can see in Tutorial 4 - Axis Control, specially in the Multiple Custom axes section.

You'll find the tutorials at TeeChart's program group.
