Example 15: X/Y scatter with spline chart and error margin indicators
For each point of the
spline, a bracket is drawn to indicate the
error margin for each point.
Steps:
1. Create a new Windows
application project (VB.NET)
2. Add Super 2d/3d Graph
Library to the toolbox pallete and drag it
to Form1.
3. Copy and paste de
following code:
Note: the code in the
Form1_Load event could be used in ASP.NET
applications as well.
