Description sandra pazos 2014-07-11 05:54:24 EDT
Using the following code, we can see that in regular or irregular ColorGrid series, the axes scales aren't calculated correctly when the CenteredPoints property is true and axes values are between 0 and 1.

procedure TForm1.FormCreate(Sender: TObject);
var x,z:Integer;
begin
Chart1.View3D:=false;
Series1.IrregularGrid := true;
 for x:=0 to 5 do
    for  z:=0 to 5 do
      Series1.AddXYZ(x/10,random,z/10);
     Series1.CenteredPoints := true;
end;

According the code the bottom axis value range should be from 0 to 0.5 instead of -0.5 to 0.1.

Using the same code with TeeChart.Net the problem isn't appeared.
 
Steema.TeeChart.Styles.ColorGrid series1; 
        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            series1 = new Steema.TeeChart.Styles.ColorGrid(tChart1.Chart);
            Random rnd = new Random();
           series1.IrregularGrid = true; 
            for (double x = 0; x < 5; x++)
            {
                for (double z = 0; z < 5; z++)
                {
                    double valuex = x / 10;
                    double valuey = z / 10; 
                    series1.Add(x/10, rnd.Next(10), z); 
                }
            }
            series1.CenteredPoints= true; 
        }
