More digits on the plot window coordinate display?

Is there a way to display more digits on the cursor readout in the lower right hand corner of the plot window? Right now my setup is only showing three digits to the right of the decimal point, which isn’t enough when I’m zoomed way in. If that description isn’t good enough to describe what I mean, take a look at the following screenshot:

http://sleepingsquirrel.org/matplotlib/low-resolution-coords.PNG

…or maybe I’m looking for a way to trace the individual displayed waveforms with the cursor, like on a digital oscilloscope, to ease in the taking of measurements. Any thoughts?

Thanks,

Greg

Re: Animation and imshow

loop through the data and call clf():

from pylab import *
from numpy import *

ion()
hold(False)

frame1 = zeros((200, 200))
frame1[20:40, 20:40] = 255

frame2 = zeros((200, 200))

frame5 = zeros((200, 200))
frame5[20:40, 50:70] = 255

for frame in data:
    m=imshow(frame)
    m.set_data(frame)
    clf()

Compilation problems on Fedora Core2.

Hi all,

Both the latest matplotlib (0.98.3) and the maintenance release (0.91.4) 
fail to compile for me with identical error msg.

I'm using Fedora Core 2, which I can't upgrade unfortunately.

I've installed python2.5.2,  numpy-1.1.1, pygtk-2.4 and they seem work ok.

The relevant line is,

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall

colorbar tick labeling

I was wondering if it is possible to change the colorbar tick labeling in 
matplotlib from numeric to text. Essentially, I want the colorbar to be a 
qualitative indicator; in the jet scheme, I'd like blue to be labeled 
as 'unstable', green as 'neutral', and red as 'stable'. I can change it so I 
just show the underlying values - colorbar(ticks = (-1, 0, 1)), but I cannot 
change the the tick labels to text. Is there any way to accomplish this? 
Thanks in advance for any help.

Animation and imshow

I'm trying to figure out how to do animated graphics in pylab using
imshow, so I made this little 'hello world' equivalent showing a
moving square over two frames.
Problem is I have to call draw twice to refresh the image. Anyone can
explain why this is so (and how to do this more elegantly)? This is
the code:

from pylab import *
from numpy import *

ion()
hold(False)

frame1 = zeros((200, 200))
frame1[20:40, 20:40] = 255

frame2 = zeros((200, 200))
frame2[20:40, 30:50] = 255

m = imshow(frame1)
draw()               # shows frame1
m.set_data(frame2)
draw()               # still shows frame1!!!
draw()               # and now it shows frame2!??

compiling problems w/ py2.6 on OS 10.4

(message was too long before, and bounced. trying again, having abridged the terminal output)

I've just installed python 2.6, and I'm having trouble compiling matplotlib.

The problem is generally the same whether I try to build it myself or use easy_install.

Here are my specs:

Python 2.6

matplotlib 0.98.3

numpy 1.2.0

on a Apple iBook G4, running OS 10.4.11.

In the past, I've had no problems getting it working with Python 2.5, although since then I've changed from tcl/tk 8.4 to tcl/tk 8.5.

Here is the output in the terminal:
