I want to plot shapefile. Shapefile is polygon. I used following code.
India=shaperead('india.shp');
longitude=ncread(filename,'lon');
latitude=ncread(filename,'lat');
mymap=pcolor(longitude,latitude,MeanJJASRain');
mymap.EdgeAlpha=0;
hold on
colorbar
caxis('auto');
title('Mean (1901-2018');
cmp=colormap;
cmp=flipud(cmp);
colormap(cmp);
mapshow(India);
hold off
Ignoring the rest, mapshow command plots the shapefile, but the shapefile is soild and filled inside. Because of this the plot from pcolor is hidden. How to make the shapefile transparent and plot only the outline?

Hi,
You could try using FaceAlpha property of mapshow to reduce the transparency of the polygons. Have a look at this example snippet.
% you can set the value of FaceAlpha from 0 to 1
% use FaceAlpha zero for total transparency
mapshow(india, 'FaceAlpha', 0)
Refer to the following link for more info on different properties of patches
