Hi,
I'm trying to plot a set of points, each point having a different color.
For the moment, I'm trying to do something like that :
for indice in range(0, points.shape[0]):
pl.plot(points[indice, 0], points[indice, 1], 'o', c =
colours[indice,:], hold = True)
where points is a numpy array

Uwe,
I don't know the answer to your question, but yesterday Rob Hetland
sent out and email entitled Creating a non-linear colormap. that
includes example code. That might help you get started.

Thanks, but I can not access this article from the mailing lists

On sourceforge the newest posting is from 23th feb.
I'm not sure what the problem with SourceForge is. I'll forward you
that email off-list.

I would like to display an image using pylab
without automatic scaling to the default size of the plot window.
How can I achieve this ?
If you want displayed image to just be a pixel dump of the actual
image use figimage

(or matlab for that matter) in my life, I was rather surprised by the
behavior and (mis)understood it as a bug.
I've always gotten by just fine in pylab without even knowing what
hold did, and simply clearing the figure by hand when needed
Complete examples always help ince we have no way of knowing what the
points data structures look like, but I'll hazard a gues. The x and y
arguments to plot need to be sequences. Ie, something like
plot([0.5], [0.5], 'ro')
It can be inefficient to plot many separate points this way -- if
Thank you, I think thatthis will solve my problem :)
I didn't know this class existed.

I guess I didn't read the following carefully:
... The aspect ratio of the figure window is that of the array
... Because of how matshow() tries to
set the figure aspect ratio to be the one of the array, ...
which would explain the behaviour below.
Why the restrictions? Seems one would
set markerfacecolor (a.k.a. mfc) = 'None' (make sure you include the
quotes).

Dear matplotlib gurus,
When I use

in matlab, it produces blue boxes for y, i.e., squares with a blue
