create contour plot

[Evelien]

Hi,

I'm trying to create a contour plot from data stored in a measurement file (lvm).

The data file consists of time (x), size (y) and a concentration corresponding to each xy.

I want to show the concentration in colour intensities and not as numbers.

I've started with the "read from measurement file", but I don't know how to convert the data that is read to a x, y and z-vector, to be able to plot it afterwards .

What graph can I use best to plot the x, y, z vector? A 3d surface Active X container?

Thank you in advance!
