Hi. I found a bug in the macos backend.
I get this error when I turn on log plotting on the Y axes; it doesn't
happen when I turn off log plotting. It also doesn't happen when I use
agg.pdf driver.
Is this a well-known problem, or should I put together a little demo
that demonstrates it?

Eric,
Thanks for addressing the side-issue. If there were a simple way to
list all of the backends, that might help?
Any idea about the main point?

Thanks, Eric. Any idea for a work-around on the bar graphs?
As far as the Mac goes, I'm happy to get you a log-in on one, if you
want.

Wow, Eric. That's a lot of stuff! Thanks for looking into this to me.
It would probably be useful to have a warning message or something if
there are 0 values for the log axes.
What do you think?

Hi. It's me again, asking about dates again.
is there any easy way to a collection using dates on the X axes?
I've taken the collection example from the website and adopted it so
that there is a use_dates flag. Set it to False and spirals demo
appears. Set it to True and I get this error:

Greetings.
I have a colleague who I have worked hard to convert from matlab to
matplotlib.
One issue that has come up is clickable graphs. He would like to be
able to click on the graphs that matplotlib produces and actually have
things happen. For example:

In working on code for matplotlib, I would generally find it easier to
provide an array of objects than to provide an array of X values and a
second array of Y values. I understand that X[] and Y[] is the way
that matlab does it, but we would find it easier to provide an array
of either tup

1. Moving to matplotlib-0.91.2 solved the problem with PDF generation
on log axes.
2. Installing matplotlib-0.91.2 on Linux required installing these
packages first:
* freetype-devel
* libpng-devel
(Those packages were NOT installed automatically by easy_install)

Is there an easy way to label bars with the value of the bar at that

I guess I can do this manually using text() and the values returned by

Thanks!

I'm new to matplotlib; I was using PyX but matplotlib seems further

One of the problems that I'm having is simply getting started. I've

I've discovered that matplotlib does boxplots, and apparently this is
what I should be using for one of the big graphs in my paper.
Two problems:
1. I need to put 45 boxplots on a single date plot. Each of the
boxes has a different amount of data that goes in it. Since the
boxplot()
Hm. thanks for the info. But it's not perfect... I get times in my
formats, but not the dates. Here is the sample code:
#!/usr/bin/python
#
# Example boxplot code
#
from pylab import *
from matplotlib.dates import MonthLocator, WeekdayLocator, DateFormatter
from matplotlib.dates import MONDAY
It would be useful if grid had two options:
drawHorizontalLines = True
drawVerticalLines = True
This way, people who look for suppressing the X or Y lines would find
it in the logical location.
