Contour map axes

[turweston]

Is it possible to draw a contour map with axes set at an angle and of different lengths?

Hello turweston,

I'm not sure to understand what are you exactly trying to do. Could you please show us a picture about it?

Hello
Most contour maps are with respect to orthogonal axes, but sometimes one needs to plot them with non-orthogonal axes i.e. axes that are not perpendicular to each other.

Hi turweston,

You can set the chart to be non-orthogonal, set rotation and elevation as desired and also change walls, axes and grid visibility, for example:

Code: Select all

uses TeeSurfa;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.AddSeries(TContourSeries.Create(Self)).FillSampleValues;

  Chart1.Aspect.Orthogonal:=False;
  Chart1.Aspect.Elevation:=290;
  Chart1.Aspect.Rotation:=350;
  Chart1.Chart3DPercent:=50;
end;
