How to plot a geographical map from 0 to 360 degree of longitude

I want to plot a map which contains the whole Pacific Ocean, but when I load the coastline of Matlab, I find that it starts from -180 to 180 degree which separate the Pacific into two parts, how can I plot the Pacific Ocean as a whole part with coastlines?

If you have the longitude and latitude values, all you need to do is to go through the longitude and convert it to a 20-380 system. That is, add 360 for any longitude <20.

Hi leon, thanks so much for your answer, plot the map from 20-380 is not difficult, here my problem is the coastlines, the longitude and latitude of the coastlines used is default by Matlab (from -180 to 180 lonitude), how to adjust the coastlines? Many thanks.
