By default, matplotlib uses a backend which requires an X connection (in this case, it is using the Qt library). So I am guessing that you are on edison and did not connect with the -X option. So if that is the case, you have two options:</div><div class="gmail_msg"><br></div><div class="gmail_msg">1) connect to edison with a -X option</div><div class="gmail_msg">2) set matplotlib to use a different backend.
