I'm trying to plot 6 plots onto A4 papersize dimensions as 3x2 images.
While I've got the plots, the y axis scale is puzzling me.  The data
is index ticker data(it doesn't go negative at all) but the scale goes
from -1000 to max index for the 2nd to 6th plot.

I had to use something like

ax3.axis([x[1], x[-1], 0.8 * y_min, 1.1 * y_max]) to fix it.

You can see the difference in the 2nd plot versus the rest.

The code is here

p.s this is my first try using matplotlib

I'm working on some computer vision algorithm and I'd like to show how a
numpy array changes in each step.What works now is that if I have a simple
imshow( array ) at the end of my code, the window displays and shows the
final image.However what I'd like to do is to update and display the imshow
window as the image changes in each iteration.So for example I'd like to
do:The problem is that this way, the Matplotlib window doesn't get
activated, only once the whole computation is finished.I've tried both
native matplotlib and pyplot, but the results are the same. For plotting
commands I found an .ion() switch, but here it doesn't seem to work.Q1. What
is the best way to continuously display updates to a numpy array (actually a
uint8 greyscale image)?Q2. Is it possible to do this with an animation
function, like in the dynamic image example? I'd like to call a function
inside a loop, thus I don't know how to achieve this with an animation
function.

It would be helpful to know which version of matplotlib you are using,
which example you are referring to (I can guess, but I would rather know
for sure) and/or a minimal self-contained example that demonstrates the
problem you are having.

I am using python 2.7 and matplotlib animations example .
when i am using gtk2 as a reference the plots works fine
but when i change the backend to gtk3 i start getting errors .
can someone help with that
how to work with animations / blit in gtk3
