Subject: 2D contour plot using vb.net

Question
QUESTION: I would like to write 2D contour plot routine in vb.net
Lets say you have four values of a function f(x,y) at four corners of a square. How do you fill the square to represent variation of f(x,y) in vb.net?

ANSWER: can you send an image of what you want to plot with sample values on each corner?

---------- FOLLOW-UP ----------

QUESTION: I am not interested in one particular image. To put it more generally, I have an array of values f(i,j) over a regular grid. I would like to draw filled contour plots.

Answer
Hi,

The above link will take you to the generic VB.net 2D drawing API.

After finding the API that suits your need you can come back to me and we can discuss it in greater detail.

Regards,
Riz
