Re: [Matplotlib-users] autoscale problem?

[Darren D. <dd...@co...>]

Hi John,

It is a bug. I suggest making the following change to ticker.py, starting at 
line 501 in version 0.72.1:

    def le(self, x):
        'return the largest multiple of base <= x'
        d,m = divmod(x, self._base)
        if closeto(m/self._base,1): # was closeto(m, self._base)
            #looks like floating point error
            return (d+1)*self._base
        else:
            return d*self._base
