Hi rojo,

You can do this programatically:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.Aspect.Orthogonal:=false;
  Chart1.Aspect.Elevation:=0;

  TrackBar1.Min:=-90;
  TrackBar1.Max:=90;
end;

procedure TForm1.TrackBar1Change(Sender: TObject);
begin
  Chart1.Aspect.Elevation:=TrackBar1.Position;
end;

Hi,

i made this already. With the trackbar you can elevate the graph.
But i also want to elevate the graph with the mouse. Therefor i use the rotating tool. But wenn i set chart1.Aspect.Elevation:= 0; and i want to elevate with the mouse in the graph. The graph jumps to 270 deg. I think becaus the rotating tool only can elevate between 270 and 360 deg.

I hope you have a solution.

Hi Rojo,

I'm afraid so. In that case, the only solution I can think of is being a sourcecode customer and modifying tool's sources to fit your needs. I'll also add your request to our wish-list to be considered for inclusion in future releases.
