How to plot tick values in-place?

Community matplotlib-users

Hello
I didn't find an answer with google or stackoverflow, maybe someone here
can help? The code:

import matplotlib.pyplot as plot
plot.plot([0, 1e-9, 0, -1e-9])
plot.show()

produces a plot in which y ticks are -1, -0.5, 0, 0.5, 1 and their
scaling is plotted elsewhere, how do I force matplotlib to plot the tics
in-place as -1e-9, -0.5-e9... so I don't have to search other parts of
the plot for potential corrections to tick values? Thanks!

I think setting the rcParam 'axes.formatter.useoffset' to False prior to
any plotting would do the trick.

plot.rcParams['axes.formatter.useoffset'] = False

Untested, though.

My matplotlib.__version__ == '1.1.1' doesn't have that neither in
matplotlib nor in plot:

>>> matplotlib.rcParams['axes.formatter.useoffset'] = False
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File
"/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/matplotlib/__init__.py",
line 660, in __setitem__
     See rcParams.keys() for a list of valid parameters.' % (key,))
KeyError: 'axes.formatter.useoffset is not a valid rc parameter.See
rcParams.keys() for a list of valid parameters.'

>>> matplotlib.pyplot.rcParams['axes.formatter.useoffset'] = False
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File

KeyError: 'axes.formatter.useoffset is not a valid rc parameter.See
rcParams.keys() for a list of valid parameters.'

Also I did find this: plot.ticklabel_format(useOffset = False) which
looks like what you suggest but that only removes offset from ticks not
scaling. Thanks
