[python-control-discuss] possible error in call to legend() from examples/genswitch.py

[Scott C. L. <sli...@ca...>]

I cannot run the example genswitch.py without modifying the calls to legend() to use tuples.  Can someone confirm my observation?  I am testing with Matplotlib version 1.1.1rc.  My proposed patch is to lines 43 and 65, which should now be

  mpl.legend(('z1, f(z1)', 'z2, f(z2)'))    # legend(lgh, 'boxoff');

and 

  mpl.legend(('z1 (A)', 'z2 (B)'))  # 'Orientation', 'horizontal');

respectively.
