Hi. I am trying to output multiple 2D graphs (subplots) in one figure
(using pylab) for each time-step that the python code runs - basically an
interactive graphs. We use the 'ion()' and 'imshow()' functions for this.
I have many graphs to chose from, but say if I chose 4 graphs to output, all
4 will output for the 1st time step, but for every additional time step only
the last graph will update. The first 3 will remain the same, as they were
in the 1st time step. Has anyone has this problem? Any suggestions?
A portion of the O-O code is below. This function is called in another
file. I tried to add notes where I thought they were helpful.
def multi_display(self, n=4):
''' displaying multiple graphs '''
ion()
m = self.displayed_multi # four input graph names (provided when
function is called)
nsub = n # no. of subgraphs/time step
for i in range(nsub): # for each subplot
p = i +1
exec ("self.subplot" + str(p) + " = subplot(2, 2, p)") # OR
subplot(2,2,p)
self.displayed = m[i]
self.display_stand() # this calls the function below with
'self.displayed' in it.
def display_stand(self): # displays individual graphs
if self.displayed == 'ht': # this is only one of the four graphs (or
subplots)
vm = 0.0
vx = 40.0
t = 'Height (m)'
imshow(self.old_ht, vmin = vm, vmax = vx,
interpolation = 'nearest')
title(t)
Thanks,
Louise
