Hi John,
Yes, that is true if the data is truly gaussian. In my case, I know that the
data have non-gaussian tails which tend to dominate the calculation of the
standard deviation. I should have been clearer in my post that what I
actually wanted to do was fit a gaussian to the truncated "central"

Hi,
Is it at all possible to have figimage draw the image OVER the top of
the plot area? Currently I can only get it to draw underneath — even
if I set the frame alpha to zero, it is obscured by the grid. This can
be seen from the test code below:

Another related question. is there some statistics function that

Unfortunately, at present you can't. The figure referencing in Sphinx
works because there is a hard-coded phase to match labels to figures
(which doesn't know about plots). I think the matplotlib plot directive
needs to write such a phase at well (should be possible using Sphinx
event hooks)

as well) -- the SVG backend already supports hyperlinks, so if possible

Looking a little further at this problem it looks like iPython was

I reattached your example in a slightly modified way. For me with current svn

Does this help you?
