Description
For some values (related to multiples of .3 and .7 it seems) drop the last tick label.
expected: the last tick to be labeled, spacing of .1 between major ticks
get: all be last label are correct
The following demonstration is assumed to be in an interactive shell with pylab imported
fig = figure()
ax = gca()
draw()
ax.get_yaxis().set_major_locator(matplotlib.ticker.MultipleLocator(0.1))
ax.set_ylim([0,.2]); draw() # works
ax.set_ylim([0,.3]); draw() # fail
ax.set_ylim([0,.4]); draw() # works
ax.set_ylim([0,.6]); draw() # fail
ax.set_ylim([0,.7]); draw() # fail
ax.set_ylim([0,1.2]); draw() # fail
ax.set_ylim([0,1.4]); draw() # failtested against master branch.

Confirmed. It looks like it is a floating-point issue. Observe:

One way to fix this is to launder the maximum value through
float(str(val)), but that seems super hacky.mdboom commentedon Jan 14, 2013
Sorry I'm just noticing this issue now -- it's a pretty serious one. @tacaswell: Can you file a PR with this commit (or is it already part of another PR)?
tacaswell commentedon Jan 14, 2013
@mdboom I didn't put in a PR before because I was not sure of it was too hackish a fix.
