Hi Brendan,
I reiterate that in polar coordinates, a negative value of "r"
does not make sense. It is confusing at best.

Hi Jianbao,
One option for getting Chaco is to install the Enthought python disctribution

Sometimes, instead of using data points with error bars, I instead use

A question for a possible new feature for Matplotlib.
First, in case there is a way to do it currently:
I often find myself plotting data with errorbars, and I would like to be able
to modify the marker, or marker size of each individual point separately. A

Hi Sean,
I just checked - the hyphenation you want does not work in LaTeX in math mode.
Try removing the "$"-signs in your string command. Then the hyphenation should
work.

Hi Chris,
I think I understand what you are asking. I think the key point is I have used

When I make my plots, I use np.hist, but then to access the data, I use
np.histogram.

Hi Thanks for the answer,
actually, I always use

I'll look into it.
Do you have an idea where I can find a description of the keyword
"format"
'%.3f' is nice, but still not scientific format...
you can use
'%.3e'
nal etc, and so could still make new names for the files.
