In stead of saving the figure by "pylab.savefig()" command, I want to get the figure in
Would you please help me to do that?
Got a little couch potato?
Check out fun summer activities for kids.

Here is an example using agg
from pylab import figure, show
import numpy as npy
# make an agg figure
fig = figure()
ax = fig.add_subplot(111)
ax.set_title('a simple figure')
# grab the pixel buffer and dump it into a numpy array
buf = fig.canvas.buffer_rgba(0,0)
l, b, w, h = fig.bbox.get_bounds()
X = npy.fromstring(buf, npy.uint8)
X.shape = h,w,4
# now display the array X as an Axes in a new figure for illustration
fig2 = figure()
ax2 = fig2.add_subplot(111, frameon=False)
