[matplotlib-devel] problem with loglog

[Perry G. <pe...@st...>]

I must be doing something stupid, but I can't get the simplest
loglog to work. For example:

>>> x = arange(10.) + 2
>>> y = x**2
>>> y
array([   4.,    9.,   16.,   25.,   36.,   49.,   64.,   81.,  100.,
121.])
>>> loglog(x,y)
Traceback (most recent call last):
[...]
    xt = self.transx.positions(x)
  File "C:\Python23\Lib\site-packages\matplotlib\transforms.py", line 621,
in po
sitions
    return  scale*(self.func(x)-minin) + self._boundout.min()
  File "C:\Python23\Lib\site-packages\matplotlib\transforms.py", line 520,
in lo
gwarn
    raise ValueError('Cannot take log of non-positive data')
ValueError: Cannot take log of non-positive data
