Define Boundary from VB2008 ?

[PCJimmmy]

I am generating data in VB2008 that results in contour plots that have concave and convex edges.

Once the plot is generated I can use Options/Define Boundary to clean up these edges.

I dont seem to find a command that will let be define the bondary from my VB program.

Am I just blind or does no such creature exist?

Thanks
Jim

Call DPlot_3DBorder. The Project1 VB.NET demo has an example that uses this function.
