Cannot plot local varibles in variable explorer when debugging

my python file:

import numpy as np
def func():
    bb = np.arange(10)
    return bb      # breakpoint here

a = np.arange(5)
cc = func()

1. put a breakpoint before return bb and debug the file
2. the program stops before return, and now two variables in the variable explorer: * global variable a = array([0, 1, 2, 3, 4]) * local variable bb = array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
3. right click on a and select plot, no problem. BUT, right click on bb and select bb, report ***KeyError: 'bb'

Plotting of variables while debugging only works with the inline backend, not with other Matplotlib backends.

@bburne, please open a new issue about that and post a simple code example that reproduces it.
