Nop... I moved it to the end if init_app() and the axes appeared. Probably because plotting happens in the main gtk loop. But in this case when the time comes to call update_from_modbus() it dumps this to the console:

*** PLPLOT ERROR, ABORTING OPERATION ***
plsym: Please set up window first, aborting operation

The reason seems to be understandable: plend() closes the context of drawing. So it comes to my original question, how is drawing done across threads?
