How to represent the spatial distribution of a parameter [message #64172]

Dear all,

I have three array X, Y and V.
X and Y represent the position, and they are not distributed uniformly
on the X-Y plane.
V represent the parameter values corresponding to their position.

I want to take some 2D figures which can represent the spatial
distribution of the parameter values.
Is there any recommended representation?

I find some figures in a paper which is shown in the web link below.

He divided the X-Y plane into small grids, and used the mean of the
parameter at the points, which are located in each grid, to represent
the parameter value in that grid.
I wander whether there is a simple way to do this in IDL.
For example, I want to use the 0.1*0.1 grid to divide the X-Y plane.
How do I plot the figures like that from X, Y and V?

Best regards,
Du
