Plot a contour map with statistical significance

Hello, i want to make a contour map and overlay the statistical significance (actually is a matrix of 0 and 1 with the same size of my matrix, which i 'd like to stiple over it, actually i want to do smt like this example in ncl http://www.ncl.ucar.edu/Applications/Images/conOncon_4_lg.png), but i can't figure any way to do it, i would appreciate any possible help. My code is as follow

axesm('robinson', 'maplonlimit', [0 355], 'frame', 'on'); % longitude from 0 to 355

geoshow('landareas.shp', 'FaceColor', 'white', 'FaceAlpha', 0,'linewidth',2)

contourm(double(lat),double(lon),dif','LineStyle','none','Fill','on')
colormap(jet(11))
colobar

the dimensions of my variables are as follow

lon: 72x1 lat: 36x1 dif: 72x36

and i have the matrix of the statistical significance h with the same dimensions as the matrix dif.
