I'm experiencing some memory issues with some python/matplotlib code. I have a large object/class containing a lot of data, and whilst using that object to create (about 30) graphs I keep running into memory errors. Here is a description of my problem: Firstly, I am able to create each graph individually. So if I run each graph creation function individually in the interpreter I get the desired result: MyClass.TypicalPlot(save=True, show = False) However, if I create a new function to run each graph function in a script then I get a "MemoryError: Could not allocate memory for path". (varies at the precise point where, but its normally after 3 or 4 graphs). I am able to run each plot function in an interpreter without issue, so I can only assume its some kind of memory/garbage collection issue. def saveAllPlots(self, comments = False): if self.comment is None: comment = False else: comment = True self.TypicalPlot(save=True, show=False, comment=comment) self.Anoth</pre> Stevenson, Samuel 2012-05-22T08:10:05 http://permalink.gmane.org/gmane.comp.python.matplotlib.general/30621 <pre>------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Suppose the programme is: from pylab import * fig = figure() ax = fig.add_subplot(111) data = rand(250, 250) cax = ax.imshow(data) cbar = fig.colorbar(cax) show() Now, fig has two axes, the main, and the bar. The command fig.delaxes(fig.axes[1]) gets rid of the bar and the ticks. Is there anything wrong with that? Of course, I knew that fig.axes[1] was the bar, but finding it in a more complicated case should not be difficult. All the best.

Ticks &lt;http://matplotlib.sourceforge.net/api/axis_api.html#matplotlib.axis.Tick&gt; have an argument "tick1On" and "label1On" but it seems I can not use these in the config file. Is that correct?

They are actually a subplot axes separate from your plotting axes. And I don't think they are very easy to remove. You could do a "cbar.axes.cla()", but that would still leave the "ticks", tick labels and the colorbar label. I am sure that there is a way to get to what you want, but it isn't immediately obvious. If someone knows how to do it, maybe we should make that into a convenience function? Perhaps cbar.remove()? Sorry I could not be more help.

I try to use mat.rcParams['figure.dpi']=300 before I plot, then the problem is that the figure which is drawn is too big for interactive check (maybe because of increase in dpi). the mat.rcParams['figure.figsize'] is still default [8,6]. The other option is that always use fig=gcf(); and fig.savefig('my_plot.jpg', dpi=300). I am suing 'Agg' backend on ubuntu system. thanks et cheers, Chao </pre> Chao YUE 2012-05-21T07:45:47 http://permalink.gmane.org/gmane.comp.python.matplotlib.general/30611 <pre>Hi Alejandro, Thank you very much for your help!
