I have a data 420*940*6 (the value of each grid varies from 0-100) and I want to plot data only inside polygon (s). lat (420*1) and lon1(940*1).
we can plot this signle page data in this way
N = length(S);
[X,Y] = meshgrid(lon1,lat1);
data= test;
for k = 1:N
idx = insidepoly(X(:),Y(:),S(k).X,S(k).Y);
hold on
plot(X(idx), Y(idx), 'r*')
end
How we can plot all pages (6) together according to values (0-100) as the attached figure?
Guide me in this regard. KSSV on 19 Feb 2019
Read about inpolygon. This will pick the values lying inside the given polygon.

We can pick the values inside polygon and plot by inpolygon/insidepoly easily but I want to plot as per the values of each grid whcih varies frim 0-100.
