I have generated the following figure, the numbers are the correlatios from the scatter plot, i was thinking of changing the colour of the numbers to be representative of the correlation.

I used the following to display the correlations:

            subplot_tight(numCols,numCols,N)%,axis square;
            A=round(corr(Long_Lat_Data(:,i),Long_Lat_Data(:,j)),3); %rounding the correlation value to 3 decimal places to save space on plot 
            set(gca,'XTick',[])
            set(gca,'YTick',[])
            str = {A};
%             axis([0 2 0 2])
            t = text(0.2,0.5,str);
            t(1).FontSize = 8;
