Re: [Matplotlib-users] Strange default choice of ylabel ticks

[Yann T. <yan...@bu...>]

Hi Per,

I think you want to use the 'ticklabel_format' method:

http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.ticklabel_format

Here's your example modified some. 'some_point2A.pdf' produces exactly the
same as the default. 'some_point2B.pdf' does not use an offset, and maybe
produces more of what you were looking for.

import pylab as pl

some_points = [0.94589396231920286, 0.94593953605915637,
0.94601787712257401, 0.94597530431819743, 0.9459922123931529,
0.94622433138703055]
pl.plot(some_points, '.-')

pl.ticklabel_format(style='plain',useOffset=0.9458,axis='y')
pl.savefig('some_point2A.pdf')
pl.ticklabel_format(style='plain',useOffset=False,axis='y')
pl.savefig('some_point2B.pdf')

-Yann
