matplotlib-users Mailing List for matplotlib

Hello everybody,

I have a question concerning the redrawing of one/several figures.

Say that I have the following (very) simple code:

ion()
f1 = figure(1)
plot([1,2,3,4])

f2 = figure(2)
plot([1,1,1,1])

and that I killed f1 and f2 figures by clicking on their respective right-top corner. Is there a way to redisplay f1 and/or f2 in the state they were just before destroying them ?

thank you very much for your help

best regards

Eric

I've boiled the code down to something small that demonstrates the problem. 
Thanks!

Hello,

I have thought of this might interesting to share. Register at
www.sagenb.org or try on your local Sage-notebook and using the following
code:

# Simple example demonstrating how to interact with matplotlib directly.
# Comment plt.clf() to get the plots overlay in each update.
# Gokhan Sever & Harald Schilly (2010-01-24)

from scipy import stats
import numpy as np
import matplotlib.pyplot as plt

@interact
def plot_norm(loc=(0,(0,10)), scale=(1,(1,10))):
    rv = stats.norm(loc, scale)
    x = np.linspace(-10,10,1000)
    plt.plot(x,rv.pdf(x))
    plt.grid(True)
    plt.savefig('plt.png')
    plt.clf()

A very easy to use example, also well-suited for learning and demonstration
purposes.

Have fun ;)

Philip:  That's an error from the proj4 c library saying that it didn't 
like one of the parameters you used to define the projection.  Since you 
didn't include the parameters you used, I can't say which one is the 
culprit.

I’ve been experimenting with basemap, and have been able to make maps using
the orthographic and polyconic projections.  When I try to generate a map
using the geostationary projection, I get the error message shown below.  I
haven’t been able to make head or tail of this message; any advice will be
appreciated.
