[Matplotlib-users] Qt4 Example timing out

[Chad K. <cck...@gm...>]

I'm following the MPL Qt4 example given at
http://matplotlib.org/examples/user_interfaces/embedding_in_qt4.html and it
looks like I am timing out somewhere in the setup.  The error I am getting
is:

RuntimeError: super-class __init__() of type MyDynamicMplCanvas was never
called

It's timing out on a function that goes and talks to a piece of test
equipment to get some data to plot.  That function takes on the order of a
second to complete and is located in compute_initial_figure(self): for the
previously mentioned class.  I will need to make these calls whenever I go
into the update routine and they may take a few seconds to update.

First, where is the "timeout" that I am violating?  Second, how do I fix
this?  Thanks for your help.
