hello,
I would like to know if there is a way to draw something like x**3+y**2<=3.
If there is not a direct way to do that, I would like to know if it could be
possible to subclass the method that plots the contours.
Best regards.
Christophe.

Hi,
Im having some trouble with this "seemingly" simple task of plotting
straight lines/fitted curves on a polar plot.
I am trying to create a plot that resembles the layout of the chart seen
below:

So far I have only been able to plot data

Hello,
I would like to make a kind of magnifying glass. So I need to have a piece of
a graph and I would like it to have the form of a disc rather than of a box.
So is-it possible to only draw in a disc (I'm searching for a fast way to do
that) ?
Best regards.
Christophe.

To put in an argument each way -- I now recognize that the PEP one

darn -- sounds like a bug/missing feature in the gzip module. Strange ,
though, unknown flags see

As far as I can see, this won't break any code, though -- Universal
newlines won't change anything with native newlines anyway.
except maybe with the gzip module...

oops -- the email process "fixed" the mixed newlines in
test_newlines.txt! At least with my client.
It's probably work if you unpack the gz though.

I don't see any elegant way to do that.
The easiest way I can think of is to use a derived line2d class.
Something like below will work. Others may have better ideas.
import matplotlib.lines
class Line2DNoInterpolation(matplotlib.lines.Line2D):
def recache(self):
matplotlib.lines.L

Thanks, your example works but what I must do so to plot for example y=cos x ? I'm a very beginner.

I took a look at the Python SVN (2.5.4 and 2.6.1) for the gzip lib. I

if mode and 'b' not in mode:
mode += 'b'

I'm embarrassed to see that I neglected to document this, but you can
pass a "resolution" keyword argument to add_axes which sets the number
of points of interpolation between each pair of data points. Set this
to 1 to disable interpolation.
This will be documented shortly.

Thanks for the help, but I can't quite see where to add the add_axes code.
Here is the code I have been using to plot, the polar plot is a subplot.
fig=figure()
ax=fig.add_subplot(111, polar=True)
ax.set_xticklabels(["E",45,"N",315,"W",225,"S",135])
ax.set_yticklabels([80,70,60,50,40,30,20,10])

Hi all,
I am trying to do the following to produce a customized contour plot:
1. Create a ContourSet from contour()
2. Retrieve vertex positions from this ContourSet
3. Modify the vertex positions by applying a coordinate transformation
4. Apply the changes to the ContourSet
5. Plot the ContourSe
