[Matplotlib-users] Potential bug in figure rendering

Hello John,

   I have run into the following minor matplotlib bug.  Using the sample 
code below, the y axis label and tick marks in the second subplot seem 
not to be in the right places.  Also on that second subplot, the first 
legend is missing when the window is initially drawn, but gets redrawn 
correctly if I use the x axis interactive scrolling buttons.

   Attached to this note is a snapshot of the figure window as initially 
drawn showing the bugs.  (I don't know whether the mailing list deals 
with attachments correctly, so I'm mailing you a copy directly.)

   The installation here is matplotlib version 0.50 running on a Redhat 
9 linux box:

[pje@amon site-packages]$ uname -a
Linux amon 2.4.20-6smp #1 SMP Thu Feb 27 09:59:40 EST 2003 i686 i686 
i386 GNU/Linux

Code:

from matplotlib.matlab import *

figure(1)
subplot(211)
plot(rand(50),'r')
plot(rand(30),'k')
plot(rand(80),'g')
plot(rand(70),'b')
plot(rand(60),'m')

plot(5 * array([1,1]), get(gca(),'ylim'), 'b')
plot(15 * array([1,1]), get(gca(),'ylim'), 'b')

axis([0,100,-2,2])
ylabel('Test me')
title('Test me')
legend(['TX Min', 'RX min', 'Pulse 1', 'Pulse 2', 'P1-P2'])

subplot(212)
plot(rand(50),'r')
plot(rand(30),'k')
plot(rand(80),'g')
plot(rand(70),'b')
plot(rand(60),'m')

plot(5 * array([1,1]), get(gca(),'ylim'), 'b')
plot(15 * array([1,1]), get(gca(),'ylim'), 'b')

axis([0,100,-2,2])
ylabel('Test me')
title('Test me')
legend(['TX Min', 'RX min', 'Pulse 1', 'Pulse 2', 'P1-P2'])

show()
