Modification in Gradient ?

[cborgeat]

Hello, I have a problem i cant understand and solve. In one previous version we use Gradient of the shape in a TmapSeries (Teechart2013 with delphi XE)

But now the code not work anymore (TeeChart 2015 and delphi 10 Seattle).

You can see exaclly wath i mean in the attached picture.

Here is the code :

Code: Select all

  Fserie := TMapSeries(Fchart.Series[0]) ;
  Fserie.Shapes.Clear ;
  Fserie.Shapes.Add ;
  Fserie.Shapes.Polygon[0].Gradient.Visible := True ;
  Fserie.Shapes.Polygon[0].Gradient.StartColor := clBlue ;
  Fserie.Shapes.Polygon[0].Gradient.EndColor := clRed ;

    FChart.BottomAxis.Maximum := 60 ;
      FChart.LeftAxis.Maximum := 40 ;

      //Premier plat et premère rampe
      Fserie.Shapes[0].AddXY(24, 18.5) ;
      Fserie.Shapes[0].AddXY(22, 18.5) ;
      Fserie.Shapes[0].AddXY(15.2, 11.5) ;
      Fserie.Shapes[0].AddXY(1, 11.5) ;
      Fserie.Shapes[0].AddXY(1, 10.5) ;
      Fserie.Shapes[0].AddXY(16, 10.5) ;
      Fserie.Shapes[0].AddXY(24, 18.5) ;

      //Jointure
      Fserie.Shapes[0].AddXY(23, 18.5) ;
      Fserie.Shapes[0].AddXY(24.2, 19.5) ;

      //Premier step dans le plat
      Fserie.Shapes[0].AddXY(26, 19.5) ;
      Fserie.Shapes[0].AddXY(26, 20.25) ;
      Fserie.Shapes[0].AddXY(28, 20.25) ;
      Fserie.Shapes[0].AddXY(28, 18.75) ;
      Fserie.Shapes[0].AddXY(26, 18.75) ;
      Fserie.Shapes[0].AddXY(26, 19.5) ;
      Fserie.Shapes[0].AddXY(26, 18.75) ;
      Fserie.Shapes[0].AddXY(28, 18.75) ;
      Fserie.Shapes[0].AddXY(28, 19.5) ;

      //Deuxième step dans le plat
      Fserie.Shapes[0].AddXY(30, 19.5) ;
      Fserie.Shapes[0].AddXY(30, 20.25) ;

      Fserie.Shapes[0].AddXY(32, 18.75) ;
      Fserie.Shapes[0].AddXY(32, 19.5) ;

      //Jointure
      Fserie.Shapes[0].AddXY(34, 19.5) ;
      Fserie.Shapes[0].AddXY(35, 20.6) ;
