Interpolated gridded data with limits

I have gridded data which I want to plot on a longitude/latitude map. I have used the following code:

pcolor(lon1,S_latitude,sum_pd') %sum_pd' gridded data
    shading interp
    colormap jet
    c = colorbar;
    caxis([0 1])
    c.Label.String = (['Sensitivity ' species_name ' (' species_unit ')']);
    hold on
    grid on
    borders('countries','k')

But using pcolor interpolate across all longitudes (see image). Is there a way to avoid this or interpolate between a longitude region?

Don't transpose the ZData. Try:

pcolor(lon1,S_latitude,sum_pd)

If you still face a porblem or if you get an error. Read about inpolygon.

[David du Preez]

The zdata must be transposed for the dimensions to work. Using inplogon gives an error because the longitude ranges between -50 to 100.

What error it shows?

[David du Preez]

The function assumes that assumes that the polygon goes from -50 to 100 and covers the 0 longitude which is the area I want to exclude.
