The function arrow() works for me (Python 2.6.5, matplotlib 99.1.2).
Perhaps something in your installation needs to be changed.
You might try pylab.Arrow() to create patches or perhaps quiver() which
draws a whole set of arrows.

Can't you do ginput(n=1) in a while loop? Ginput needs to end at some
point, right? Initiating a never ending loop seems like the wrong
solution for any real-life problem.

What I usually do is to clear the axis (using cla() only) right after
creating or accessing it (either with figure() or subplot() or similar
magic):
from pylab import *
fig = figure(num=1)
for example in range(5):
cla()
plot(rand(100))
savefig('test-%d.png'%example)

Hi all,
When creating a new colormap, with a script based on the example given here:
http://www.scipy.org/Cookbook/Matplotlib/Show_colormaps
When plotting the data, and when adding the colobar, I get this error:
In [27]: Exception in Tkinter callback
Traceback (most recent call last):
File "/u
Try this:
from pylab import *
from numpy import *
Z = random.randn(100,100)
figure()
subplot(1,2,1)
imgHandle = imshow(Z, cmap=cm.gray)
scatter(random.rand(10)*100,random.rand(10)*100)
colorbar(imgHandle)
title('Hello')
show()
By the way, I find jet a bad colormap to represent scientific data:

Actually, it does not draw the polygon edges, but leaves small gaps
between them. Through those gaps you can see the background. (This also
happens with polar plots and other polygons by the way.) I consider this
a bug, though there are ways around it. For contour plots one can plot
two contour
Can't word handle eps files? In the WYSIWYG it will show the embedded

however (including to pdf) it uses the vector version. Of course, eps

Dear Chris,
That site really cleared the basic resolution stuff up for me, and it
was pretty much as I expected. Your remark about how imshow() works with
SVG made me wonder. Might it be that the output of imshow() is set in
pixels so that when I increase the dpi of the total figure, the subplots

I have the same symptoms on my Ubuntu 6.06 using python 2.4 and
matplotlib 0.82-5. Where did you find matplotlib 0.87-5 though? It's not
in the repositories as far as I can tell. I use synaptic for upgrading.

Try opening a python shell and type:
from pylab import *
a = [1,2,3]
a
What is a? Is it an array? Make sure you create an array by giving a
command like this:
a = array([1,2,3])
