Axes.Depth.Title.Angle

Post by xsLiu » Tue Sep 15, 2020 7:13 am

In a 3D Chart, I want that Axes.Depth.Title is arranged along the axis (See the red line with an arrow in the attached figure). Although the following codes were used, it still does not work. How to solve this problem?

Code: Select all

procedure TfrmUPlot3D.TheChartBeforeDrawSeries(Sender: TObject);
var
  aStart, aEnd: TPoint;
  aStart2D, aEnd2D: TPoint3D;
  aAngle: Double;
begin
  with TheChart do
    begin
      aStart2D.X := Axes.Depth.PosAxis;
      aStart2D.Y := ChartRect.Bottom;
      aStart2D.z := Axes.Depth.IStartPos;
      aStart := Canvas.Calculate3DPosition(aStart2D);

      aEnd2D.X := Axes.Depth.PosAxis;
      aEnd2D.Y := ChartRect.Bottom;
      aEnd2D.z := Axes.Depth.IEndPos;
      aEnd := Canvas.Calculate3DPosition(aEnd2D);

      aAngle := ArcTan2(aEnd.Y - aStart.Y, aEnd.X - aStart.X);
      Axes.Depth.Title.Angle := 360 - Round(aAngle / TeePiStep);
    end;
end;

Chinese characters are displayed on the GLCanvas in messy codes. Please find the attached file, and see Chart.Title, Chart.Legend, Axes.Title.
Any suggestions? Would you like to give me an example? Thanks a lot!

Code: Select all

  Chart1.Canvas := TGLCanvas.Create;

If I don't use GLCanvas, is there any other way to arrange Axes.Depth.Title along the axis?

This is precisely one of the points to consider in #2272.
