Hi all,
I'm having problems doing this. I have 3 arrays: data, x, y. All of them are 1D. I want to create contour plot of Data with axis x and y.
I tried
contour,data,x,y,/irregular
but the triangulation it produces gives me a too irregular contour that doesn't represent the data I have.
Is there any other way of doing this?
Thanks!

You can take more control over the triangulation the Contour
plot is doing, by using the Triangulate/Trigrid method
yourself. Or, another (usually disappointing) option is
to try to figure out how to use the GridData function
is some reasonable amount of time.
Here is an example of using the Triangulate/Trigrid
approach:
