matplotlib-users Mailing List for matplotlib

   I see that I've been immortalized on the SciPy MatPlotLib Cookbook web
page for my enquiry on plotting S- and Z-curves. The Boltzman function
serves very well for that purpose, and I've tweaked the example code to
allow me to pass in the two endpoints and the midpoint for each of these
curves.

   Now I need to plot normal curves (a.k.a. Gaussian or bell curves,
depending on the background of the speaker/writer). I see that SciPy has a
class for the normal curve in its stats package, and that the curve shape is
defined by the mean and standard deviation.

   My need is to draw these curves based on the midpoint (== mean) and tail
endpoints (which are not the same as the s.d.). I can copy -- or call -- the
SciPy class from my application code, but I don't know if this is the most
parsimonious approach. Your thoughts are appreciated.

   These plots will be used in two different media, and it two forms. Within
the wxPython application I want to display each curve on one panel, and the
set of curves related to one linguistic variable on a second panel. Then I
need to have the set incorporated into a ReportLab report in .pdf.

Hi list

It looks like I cant change any properties of a matplotlib figure/axis
after I saved the figure
using the GUI. At least I cant use gca(), and gcf(). It works fine if
the save (e.g., figure.savefig('foo'))
was performed in the oo interface

Does anybody else have a problem with this (code below)?

import pylab as p
p.scatter([1,2,3], [1,2,3])
*save figure using the toolbar-button*

# then ... oops, I forgot something, and I need to change some properties
# trying to get my axes
ax = p.gca()
# and this pops up a new figure with new axes

---

# the oo seems to work just fine (if I only knew that ... )
p.scatter([1,2,3], [1,2,3])
fig = p.gcf()
fig.savefig('/tmp/tull')

ax = p.gca()

I am on Ubuntu feisty with numpy 1.01, matplotlib 0.87.7, using Ipython 0.7.3

Darren,

   Thank you. I assumed that to be the case, but it's nice to have that
confirmed.

   On the original issue, changing from the default GTKAgg to WXAgg removed
all the GTK (cairo, libpangocairo) errors I was seeing. Since I want WXAgg
as the default anyway, this works out nicely.

   Now to learn matplotlib for our application. I know I'll be back with
questions. :-)

Happy Thanksgiving,

Rich

They are all defaults. We prefer to ship default rc files that are commented 
out so it is easier to track down bugs, it makes it easier to keep track of 
any nonstandard settings.
