I am trying to plot correlation maps that show the correlation between a region and a given climatic driver. I want to colour the polygons of the region according to their correlation indices with a specific driver. How is this best achieved. I have been using point features until now and then plotting using scatterm function which allows one to give the correlation data as criteria for the colours eg.
h1 = scatterm(lats, lons, 100, corrdata(m,:),'o','filled');
Is there a way to do a similar thing but using polygon shape-files instead (different areas in the world)? For example, if I calculated the correlations between an observed phenomena in each of the 50 countries in Europe and MSL pressure, how can I plot and colour the different polygons (in a shape-file) based on these correlation values?
Thanks in advance
