Hi all,
I've noticed that when I save my figures using savefig the memory is
not immediately released. For example, in pseudocode,
times = get_times()
for var_id in var_list:
Plotting.figure()
var_values = get_values(var_id)
pylab.plot(times, values)
Plotting.savefig(var+'.png', dpi=150)
Plotting.close()
This pseudo code loops over a list of variables, gets their values, and
saves a plot for each one. The variable list has hundreds of items. If
I run the code like this, the memory usage grows very quickly until
python crashes. If I comment out the savefig line, or shorten the list
of variables, the code completes without error.
Can anyone suggest how I might write this differently so that I can
process the long list of variables and save the figures? Is there any
way to force the program to release memory once the figures are saved?
I'm using matplotlib 0.90.1 and python 2.4 on windows XP.
Thank you,
--Jordan Atlas
