Hi,
I got an old script and i am modifying it. Below is my script
for i=1:2
h= figure;contourf(X',Y',damp_matrix(:,:,i),1000,'EdgeColor','none');
colorbar
xlabel('Wind direction [deg]');
ylabel('Azimuth position [deg]');
end
Here Positive values are shown by red and negative values are shown by blue. I need the reverse of this, positive values should show blue contour and negative should show red contour.
Please help

At first, you can choose a colormap with the command 'colormap', the default one is 'jet' but you can also use something else like 'hot', e.g. colormap(hot). In your case you need to invert the colormap using 'flipud', you can use the following command: colormap(flipud(jet))
