I want to make color map from text file which contains three columns( 1st is latitude, 2nd is longitude, 3rd is temperature). I have accessed to this code which reading and creating color map from text file (1-1000.text)
fid = fopen('1-1000.txt');
C = textscan(fid, '%f %f %f')
fclose(fid);
f = {'lat', 'long', 'temp'}
S = cell2struct(C,f,2);
N = 1000;
[Xi, Yi] = meshgrid(linspace(60,80,N),linspace(20,40,N));
Ci = griddata(S.long, S.lat, S.temp, Xi, Yi);
colormap ('hot')
imagesc(linspace(60,80,N),linspace(20,40,N),Ci);
xlabel('Longitude');
ylabel('Latitude');
colorbar
I have shapefile of Pakistan(my data is of pakistan) and i want to show this color map variation over the pakistan. But have no idea how to set the background of the color map.
