Hello.
The title is my question.
I am using SAGE in terminal of Mac OSX.
When I input the latter plotting command NEW plotting window opens.
For example,
sage: G=graphs.CompleteGraph(2)
sage: G.plot() <--------- the first window open
sage: G.add_vertex(3)
sage: G.plot() <--------- the second window open
I want to view only one plotting window.
How can I do?
