Re: [sage-support] How to close a plot.
Hi group, Just in case anyone else posts, against this issue, I need to clarify that my OP was about plotting not saving without plotting. The issue was to produce a plot each time a loop is transversed, without leaving behind plots from previous iterations of the loop (in practice this could produce thousands of plots). The 'solution' I gave above (by saving pdf files) is simply the most effective solution (that I have been able to come up with, that works on my system). Any other solutions are welcome. Thanks for your interest in this issue.

Re: [sage-support] How to close a plot.
Hi Group,
Thanks for all the advice, it has proved very useful (especially Michael
Orlitzky's suggestion regarding .pdf files). In case the solution is of use
to others, see below -
As an example I use a file containing code such as -
import time
for i in range(1, 11):
p=plot(sin(i*x))
p.save('*path/file_name.pdf*')
time.sleep(2)
and 'attach' it to a sage session running on a local sage server. Each
time the plot is saved it overwrites the previous version. The pdf reader
on my system (Ubuntu gnome, which seems to use 'evince' at the pdf reader)
redraws the plot when the file to be plotted changes (I do not know if all
pdf reader behave this way).
Therefore, all I need to do to get a running updated plot (without leaving
behind thousands of previous plots), is to run the code above, and open the
pdf file for viewing.
Thanks again for the assistance,
Ron

Something like this works, but I broke my sage installation so I can't
test it:
p = plot(sin(x))
p.save('sin.pdf')
Other file extensions work somewhat magically if I recall.

[sage-support] How to close a plot.
Hi group, A simple question (if the answer is just rtfm, just say so). I am opening a plotting window (In a script that I am attaching to a notebook with say – show(plot(sin(x))) is within a loop. I wish to replace the plot each time the loop is transversed. So need to close the plot (otherwise I would end up with thousands of plots). I understand that the default plotting system in sage is matplotlib, which closes a plot with the function “close()”. However, I have tried many variations of close, plot and show, but nothing seems to close the plot. I get a variety of error messages, that basically boils down to, close() is not a valid option. Apologies as I am sure the solution must be very simple. Thanks -- You received this message because you are subscribed to the Google Groups "sage-support" group.
