It is hard to know what is wrong when we do not know how the
wrapper around the function works. The error could also be in
ConstructFigName or ConstructFigPath. Also please send the
specific error message when asking for help as that significantly
helps in tracking down the error.

Hi,
I am using matplotlib with python to generate a bunch of charts. My
code works fine for a single iteration, which creates and saves 4
different charts. The trouble is that when I try to run it for the
entire set (about 200 items) it can run for 12 items at a time. On
the
13th, I get an error from matplotlib that says it can't access data.
However, if I start the program at the point it failed before it works
fine and will create the charts for the next 12 before failing. I
assume that I am not closing the files properly somehow or otherwise
misallocating memory. I tried just reimporting pylab each iteration,
but that didn't help. This is the function that creates a chart:
#create and save the figure
def CreateFigure(state, facility, unit, SO2, increment, year, P99):
size = len(SO2)
#Create Plot
figure(1, figsize=(10,8))
bar(range(1, size+2), SO2, width=0.1, color='k')
grid(True)
xlim(0,size)
ylim(0, 1.1*SO2[-1])
ylabel('SO2 [lb/hr]')
heading = ConstructFigName(state, facility, unit, increment, year)
title(heading)
#set handles
xticklines = getp(gca(), 'xticklines')
xgridlines = getp(gca(), 'xgridlines')
xticklabels = getp(gca(), 'xticklabels')
yticklines = getp(gca(), 'yticklines')
#set properties
setp(xticklines, visible=False)
setp(xgridlines, visible=False)
setp(xticklabels, visible=False)
setp(yticklines, visible=False)
axhspan(P99, P99, lw=3, ec='r', fc='r')
ax = gca()
#P99 = str(P99)
P99 = '%0.1f' % P99
text(0.01, 0.95, '99th Percentile: '+P99+' lb/hr',
transform=ax.transAxes)
figpath = ConstructFigPath(state, facility, unit, increment, year)
savefig(figpath)
close()
Can you see the problem?
thanks,
