Please forgive the newbieness of question.
I am generating interactive plots using matplotlib as suggested by
cookbook, which writes a file and then pulls it into a view. My question
is whether that file is protected from other users seeing it. A second
question is whether, as I hope, the plot file will go away after the
session is over.
The application takes in financial planning data, does some calculations
in a module and then writes both a message and a graph to the screen.
Current graph is a dummy.
