Have you tried 

plt.show(block=False)
?

Re: matplot plot hangs

[Andrew Z]

nope. it doesnt:

I added print-s after each line and that produced:
[az@hp src]$ cat ./main1.py
import matplotlib.pyplot as plt
print("imported")
plt.plot([1,2,4,1])
print("plot is done")
plt.show()
print("show is done")

[az@hp src]$ python3.5 ./main1.py
imported
^C^Z
[1]+  Stopped python3.5 ./main1.py

Hi,
sorry if it is too trivial, just to make sure, do you have a call to
"show()" the resulting plot in the code?

An elementary plotting code might be e.g.:

import matplotlib.pyplot as plt
plt.plot([1,2,4,1])
plt.show()

Does this work in your environment?

It was not quite clear, what do you plan with interactive drawing, or
whether you are using e.g. plt.interactive(True) already - this might
be a problem as there could be collisions or the plot window is closed
after the standalone script finishes.

Wolfgang,
 I tried to ran from ide with no rwsults, so now im trying from a terminal
in xwindow.
The .plot is the last line in the script and it does hang trying to execute
it.

Hi Andrew,

>From which environment are you trying to run the example? In the terminal,
from within some IDE, inside a jupyter notebook?

Are you sure the script "is hanging on plt.plot(t, s)" and not after that?

Best,
Wolfgang

Installed matplotlib into user's directory.
tk, seemed to work -

up just fine.
but when trying to run the simple plot (
https://matplotlib.org/examples/pylab_examples/simple_plot.html) the script
is hanging on;

plt.plot(t, s)

attempts to

Hi Andrew,

From which environment are you trying to run the example? In the 
terminal, from within some IDE, inside a jupyter notebook?


Are you sure the script "is hanging on plt.plot(t, s)" and not after that?

Best,
Wolfgang

Stefan,
I intentionally tried to use the qt backend that i do not have. I wanted to
check i the switch was working (or not).

All i want at this point is to use (seemed to be default) tkagg.
