I am using pcolor to plot data. The code is written below and the image generated is also shown.
This scale does not show the trends properly. How can I change the scale so that the same scale (-15 to -50) has more colors included in it and the contrast is better on the graph?
Code
[freq_grid,rpm_grid] = meshgrid(freq,RPM100_mean);
figure
s=pcolor(freq_grid,rpm_grid, log(resp1)');
shading interp
colorbar
The three .mat files 'freq', 'RPM100_mean' and 'resp1' have been attached below if requried.
Thank you!

I would suggest experimenting with different colormaps, such as colormap(hsv)
