SubAxis?

I'd like to try the new SubAxis functionality but I wasn't able to find any examples or documentation.
Any pointer?
For example, how would you add a year and month bottom and subaxis?
Thanks,
Steve

Hi Steve,
You are right, we need to publish some example about new functionality. We are preparing them but we didn't want to delay the release for XE5 until the examples were ready.
Back on the subject, there is some overview information in the
Whats New? page, search for
SubAxes. A simple code example to achieve what you request would be this:
Code: Select all
uses Series;
procedure TForm1.FormCreate(Sender: TObject);
var
Years : TChartAxis;
begin
Chart1.AddSeries(TFastLineSeries).FillSampleValues(10000);
Chart1[0].XValues.DateTime:=True;
Chart1.View3D:=False;
Chart1.Axes.Bottom.Increment:=DateTimeStep[dtOneMonth];
Chart1.Axes.Bottom.DateTimeFormat:='mm';
//Chart1.Axes.Bottom.Items.Format.Transparent:=True;
Years:=Chart1.Axes.Bottom.SubAxes.Add;
Years.Increment:=DateTimeStep[dtOneYear];
Years.DateTimeFormat:='yyyy';
Years.Visible:=True;
end;

So when Axis.DateTime = true do you add points as XY points?
Thanks,

Hi Steve,
Yes, X values will be interpreted as TDateTime values though. You'll find some more details in tutorial 4. Tutorials can be found at TeeChart's program group created by the binary installers.
