Change interval values of lat and lon

I am using pcolor to plot geographic data. Doing pcolor(double(Lon),double(Lat),X) displays values of longitude as 0, 50, 100, 150 etc and latitude as 0, 20, 40, 60 etc. How can I change the values of lat and lon displayed so they are in intervals of 30 for longitude (instead of 50) and 15 for latitude (instead of 20)? Will the grid lines also change?

Ticks and labels are axes properties. You can get a list of what the current settings are by running

get(gca);

You can see what options are are available for these properties by running

set(gca);

For tick locations, you can set them to whatever you want. For example:

set(gca,'xtick',[30 60 90 120],'ytick',[15 30 45 60]);

Use the functions xticks and yticks.
