How to set Spline chart 3d in .NET

Question

I am using the chart component of .NET Framework 4.5 in C#.

When I fill that component with values that do not have the same gap to each other and set the ChartArea.Area3dStyle.Enable3d property to true, there is almost no impact on the chart until I equalize the gaps between the values in the series.

DataPoint dataPoint1 = new DataPoint(0D, 20D);
DataPoint dataPoint2 = new DataPoint(1D, 30D);
DataPoint dataPoint3 = new DataPoint(200D, 50D);
DataPoint dataPoint4 = new DataPoint(300D, 20D);
DataPoint dataPoint5 = new DataPoint(400D, 0D);
DataPoint dataPoint6 = new DataPoint(500D, 30D);
DataPoint dataPoint7 = new DataPoint(600D, 10D);
DataPoint dataPoint8 = new DataPoint(700D, 10D);

series1.Points.Add(dataPoint1);
series1.Points.Add(dataPoint2);
series1.Points.Add(dataPoint3);
series1.Points.Add(dataPoint4);
series1.Points.Add(dataPoint5);
series1.Points.Add(dataPoint6);
series1.Points.Add(dataPoint7);
series1.Points.Add(dataPoint8);

chartArea1.Area3DStyle.Enable3D = true;

Answer 1

You can set various parameters here. The one that directly makes up for the automtic downscaling with your large x-values is PointDepth

chartArea1.Area3DStyle.Enable3D = true;
chartArea1.Area3DStyle.PointDepth = 999; // pick a value you like

The best way to explore the many wonders of the Chart control is to play with it in the designer. When you have found a good setting you can go to the yourForm.Designer.cs file and look at the generated code; while you are not advised to fool around with it is a valuable resource for many obscure settings..

Unfortunately the maximum PointDepth is 1000 and with x-values larger than 300-500 the 3D-effect is still rather weak. Maybe you can downscale your values?
