How to create a scatter plot with three variables?

Hello,

I have a set of data (pressure, temperature, count)->(x,y,z). Is there a way to plot this in 2D with the z plotted in colors based on the values of the counts?

Thanks!

you should use scatter, something like this:

psz = 23;
scatter(x,y,psz,z,'filled')

That should give you something to start with. Have a look at the help and documentation for more details.

Thank you! I think this is what I'm looking for.

One more thing to keep in mind is the matlab command lookfor - when you cannot find/remember the name of a function you can always search with lookfor:

lookfor scatter
