Hi all,
I'm using matplotlib 1.0.1 from the enthought python distribution. When I
try to use pcolormesh is ignores anything I give it for linestyle (always
solid) and edgecolor (always black), as well as any non-integer linewidth.
All these options work as I expect if I just use pcolor. An example script
follows. Am I missing something? I would just use pcolor, but it takes
minutes to render my data as opposed to seconds for pcolormesh.
#!/usr/bin/env python
import numpy as np
import pylab as pl
x=np.linspace(0,10,20)
y=np.linspace(-5,5,25)
X,Y=np.meshgrid(x,y)
z=np.sin(Y)+X**1.1
pl.subplot(311)
pl.pcolormesh(X, Y, z, edgecolor='g', linewidth=0.5, linestyle='dashed')
pl.subplot(312)
pl.pcolormesh(X, Y, z, edgecolor='g', linewidth=1, linestyle='dashed')
pl.subplot(313)
pl.pcolormesh(X, Y, z, edgecolor='g', linewidth=2, linestyle='dashed')
pl.show()
pl.subplot(311)
pl.pcolor(X, Y, z, edgecolor='g', linewidth=0.5, linestyle='dashed')
pl.subplot(312)
pl.pcolor(X, Y, z, edgecolor='g', linewidth=1, linestyle='dashed')
pl.subplot(313)
pl.pcolor(X, Y, z, edgecolor='g', linewidth=2, linestyle='dashed')
pl.show()
Thanks,

Hello,
I have a pcolormesh() plot that I would like to update when a user presses a
key. Basically there are data files from 0..N and I want to update the plot
to the next frame when a user presses the 'right' arrow. I have the keypress
event working, I just don't know how to 'update' the data for the
pcolormesh.
I'm pretty new to matplotlib, so if anyone could help with this it would be
greatly appreciated!
Thanks! (Code snippet below)
def press(event):
	if event.key=='right':
		data2D = readDataFile() #updates data2D
 #update pcolormesh somehow??
		fig.canvas.draw()
#X,Y,data2D are initially set here...
fig = plt.figure()
fig.canvas.mpl_connect('key_press_event', press)
ax = fig.add_subplot(111)
plt.pcolormesh(X, Y, data2D)
plt.colorbar()
