title: return values of subplot
body: <p>Currently I trying to get myself acquainted with the matplotlib.pyplot library. After having seeing quite some examples and tutorial, I noticed that the subplots function also has some returns values which usually are used later on. However, on the matplotlib website I was unable to find any specification on what exactly is returned, and none of the examples are the same (although it usually seems to be an ax object). Can you guys give me some to pointers as to what is returned, and how I can use it. Thanks in advance!</p>
