Hi, I found a minor bug, feel free to ignore it :) . If the vertical scale of a plot has numbers ~1E-6 the ylabel won't be visible. Example script: #--- import matplotlib.pyplot as plt import numpy as np x = np.arange(-10.0,10.0,0.1)

[Matplotlib-users] colorbar with 2 different scales

Is it possible to create a colorbar with different scales on each side? Example: a temperature colorbar with celcius values on the left side and farenheit values on the right side. If so, how could this be done? Please help, Thanks, P.Romero

In regards to my previous example, the lambda function magic is unnecessary, instead of: gobject.idle_add(lambda iter=animate(): iter.next()) It is simply adequate to do: gobject.idle_add(animate().next) Which is much simpler. My apologies for over coding the solution. -- Nathaniel

A quick but not necessarily accurate answer: Don't use Python 2.6. Use Python 2.5. I don't think matplotlib has been 'certified' for 2.6 yet. I suggest (1) uninstall Python 2.6 and numpy for 2.6. (2) Install Python 2.5 and numpy for 2.5 (3) Install matplotlib for 2.5 Constantine
