We need to develop scatter chart as shown in below screenshot:

In TeeChart we used Points series to achieve the same, but we are not getting the desired result as shown in above screenshot.

By manually setting teechart properties using TeeChart Editor, it is possible to achieve desired result as shown in below screenshot:

But we need to achieve the same programmatically at run time (instead of design time) by setting the axis relative position according to (0,0) coordinates.

I think the code you need you should already have in the following method:
Code: Select all
private void InitializeComponent()
which is in the e.g. Form1.Designer.cs unit. That is to say that all changes to TChart made by the Chart Editor are written to the InitializeComponent() by the Visual Studio designer.

Hi Christopher,
This is not as required. Nevertheless we found the way to solve this programmatically. We added following code snippet which solve our problem:
Code: Select all
ColorLine vertiColorLine = new ColorLine(tChart1.Chart);
vertiColorLine.Axis = tChart1.Axes.Left;
vertiColorLine.Value = 0;
vertiColorLine.AllowDrag = false;
ColorLine horizColorLine = new ColorLine(tChart1.Chart);
horizColorLine.Axis = tChart1.Axes.Bottom;
horizColorLine.Value = 0;
horizColorLine.AllowDrag = false;
this.tChart1.Axes.Left.AxisPen.Visible = false;
this.tChart1.Axes.Left.MinorTicks.Visible = false;
this.tChart1.Axes.Left.Ticks.Visible = false;
this.tChart1.Axes.Bottom.AxisPen.Visible = false;
this.tChart1.Axes.Bottom.MinorTicks.Visible = false;
this.tChart1.Axes.Bottom.Ticks.Visible = false;
Check out the final output as shown below:
