make a better map

hi, how can i edit and change the colormap to make it better?

this is my script:

ax = axes();
Spi3=permute(New_freq,[2 3 1]);
pcolor(lon,lat,Spi3);
shading interp

thank you in advance!

It depends what you mean by "make it better". You can set the colormap using colormap(). There are a number of built-in colormaps, and there are many custom colormaps on the File Exchange. You can make your own or customize existing colormaps using colormapeditor().

You should try:

shading flat

instead of the interp option. You will have to accept the fact that you only have data in a 32-by-20 matrix, that will limit the detail in regions with gradients and structure.

If you want much neater display you will have to gather data with higher resolution, if you're "lucky" you might get a bit neater presentation by interpolating the data to a finer grid - this implicitly makes the assumption that Spi3 varies according to the interpolation-method of your choise between the data points.
