Map data matlab plot

Plotting Map in Matlab with the colorbar and NaNs set as transparent white.

Just call it with the lat,lon and Z (same size), and do caxis of your desire at the end. Voila!
Save it.

function hhf = mapme(Latitude, Longitude, Z)
hhf = figure
load coast
latlim=[floor(min(min(Latitude))),ceil(max(max(Latitude)))];
lonlim=[floor(min(min(Longitude))),ceil(max(max(Longitude)))];
ax = worldmap(latlim, lonlim);
pcolorm(Latitude, Longitude, Z);
geoshow(lat, long,'Color', 'black' )
colormap;
set(gcf,'Color','white')
% map2 = colormap; map2( 64, : ) = 1; colormap(map2);
