[Matplotlib-users] Clearing A Figure (I Know That This Has Been Posted Before But I Does Not Work For Me)

[Thistleryver <mh...@ec...>]

I am attempting to run a lot of tests automatically and generate a graph for
each one.  However, at the moment, the previous graph remains on the figure
and the next plot is drawn over it.

I have read extensively the documentation and I have tried a whole lot of
different commands but to no avail.  In the previous post it said to use
pylab.clf() which is exactly what I've been trying to use.

So far I have used pylab.cla(), pylab.clf() and pylab.close() although I
believe that this only closes an open figure window.  I have no idea why it
is not working now especially since it would appear that my question had
already been answered in both the documentation and the forums.

I am using Python 2.6.4 on Ubuntu Linux.

Here is the relevant code I am using:
	pylab.plot(xAxis, TrainingPoints, 'b-')

	pylab.plot(xAxis, TestPoints, 'r-')

	pylab.xlabel('Epochs')

	pylab.ylabel('Sum Squared Error')

	pylab.title('Plot of Iris Training Errors')

	outfilename = str(int(LEARNING_RATE)) + ".png"
	print outfilename
	pylab.ylim(ymin=0)
	pylab.savefig(outfilename)
	pylab.cla()
	pylab.clf()

I really hope one of you can spot an error otherwise I am completely stuck.
