   Please post an SSCCE: http://sscce.org/

   Also, I assume you mean "appears" instead of "applies"?

   import matplotlib
   import numpy as np
   matplotlib.use('nbagg')
   import matplotlib.pyplot as plt
   x = np.linspace(0,10,10000)
   y = np.sin(x)
   plt.plot(x,y)
   plt.show()

   Yes, I meant `appears'

   Also, which version of matplotlib and ipython are you using, and on which
   system (linux? mac? windows?). Also, it might be relevant to know which
   version of tornado you are using

    I can not replicate this with ipython (2.3.1) + mpl (1.4.2) installed from anaconda, trying with master now.

    • mpl master + ipython 2.3.1 work
    • mpl master + ipython master does not

    So something changed over on their end.

    We should be insulated from that an we are using Comm objects to deal with the actual wire transfer. I suspect something has become crossed in how the comm is built/registered.

    This fits why there is no image (the send on the mpl side is talking to a non-existent comm) and the error messages from the python side on mouse events (it is also talking to a non-existent comm).
