matplotlib with numpy

Hi

I am trying to get matplotlib working with numpy. When trying a
simple plot, I get the following error:

/home/stefan/lib/python2.4/site-packages/matplotlib/lines.py in set_data(self, *args)
    274 my = ma.getmask(y)
    275 mask = ma.mask_or(mx, my)
--> 276 if mask is not ma.nomask:
    277 x = ma.masked_array(x, mask=mask).compressed()
    278 y = ma.masked_array(y, mask=mask).compressed()

AttributeError: 'module' object has no attribute 'nomask'

In [29]: matplotlib.__version__
Out[29]: '0.86.2'

In [30]: numpy.__version__
Out[30]: '0.9.3.1881'

I suppose ma.nomask does not exist in numpy. What is the best
workaround?

Thanks for your time.

MPL 0.86.2 is tested against numpy 0.9.4, so could please test with
that release and let us know if you still have problems?

Thanks,

Thanks, Charlie. I tried 0.9.5.2024 and it works fine.

Cheers
