Hi,
I created a map using pcolor. The map has longitudes starting from 0 to 360. I want that the map starts from -180 to +180 that the greenwch will be the center of the map.
The map come from a necdf file with latitudes, longitudes and precipitation.
map=pcolor(map_longitude,map_latitude,precipitation_change)
