In the following example the coordinates of the mouse cursor displayed in the pylab window belong to the second y-axis. But I would prefer to have the coordinates of the first y-axis to be displayed. Is this possible? import pylab as mpl mpl.plot([1,3,2]) mpl.twinx() mpl.plot([400,50,100]) mpl.show() Ciao Andreas |

You can see what happens if you don't do this by omitting the calls to set_frame_on, and then verifying that the second line does not show up (because the original axes' frame patch is blocking it. best, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7 |

I do not get a reversed list of axes. This is the output of the example code below: [<matplotlib.axes.AxesSubplot object at 0x8d8fb4c>, <matplotlib.axes.Axes object at 0x8f633ec>] [<matplotlib.axes.AxesSubplot object at 0x8d8fb4c>, <matplotlib.axes.Axes object at 0x8f633ec>] BTW, what's matplotlib.axes.AxesSubplot? I couldn't find this class. Ciao Andreas import pylab as mpl mpl.plot([1,3,2]) mpl.twinx() mpl.plot([400,50,100]) f = mpl.gcf() print f.axes f.axes[0].set_frame_on(False) f.axes.reverse() f.axes[0].set_frame_on(True) print f.axes mpl.show() |

Traceback (most recent call last):
File "t5.py", line 13, in <module>
f.axes = [f.axes[1],f.axes[0]]
AttributeError: can't set attribute
I've tried it with matplotlib 1.0.1 and 1.1.0. Same error message.
Python is 2.6.4.
I'm stumped ...
Ciao

What does: Import matplotlib print matplotlib.__version__ print matplotlib.__file__ outputs for your v1.1.0 installation and your v1.0.1 install? Ben Root |

Then I removed matplotlib/ and installed it again. But the error stays the same. Ciao Andreas |
