[Matplotlib-users] How to pause prgoram from graphical screen

[Roland H. <rh...@ya...>]

I'm reading a serial port and plotting the acquired data using TKagg with the plot() command.  This gives me a nice graphical screen that updates as the data arrives.  What I would like to do is be able to pause the entire program occasionally as I need to make changes on the system that the RS232 is reading, then begin plotting again.  Is there a way to get a pause button the TKAgg toolbar?
Thanks!

Yes, take a look at the embedding_in_tk*.py examples at

It looks like those examples suspend operation while waiting for a click, after going to mainloop().

On a related note, after I use pylab.plot() to draw the screen, the toolbar is inaccessible unless I also use show(), which then halts the program until I close the window.
