density plot at certain points

Show all headers | View raw

Hello GnuPlotters!

I have a c++ code which generates 36 point with their X,Y coordinates (X= column and Y= column ). There is a quantity that I calculate at each of this point (e.g say density) which is then stored as 3rd column. Now I have this data file. 

Q: How can I generate a pm3d plot which shows a circle of attributed radius to each of (X;Y) points and its color attributes with the density number in that point? As the simplest case, imagine we want to generate checkerboard pattern but with a certain circles and disconnected.

When I use pm3d map it gives me a blurry image which connected border between points, i.e does not tale into account the fact that points are separated.

I know vaguely that Matlab fill function would do something like this but I dont have experience with Matlab. Any help from wonderful Gnuplot is appreciated!

Cheers,
Reza
