New Development: No

JIRA Issue: Yes (CAS-3749)

Ready for Test: Yes

Interface Changes: No

What Interface Changed:

Test Programs: an interactive test

  1. load casapy (or standalone asap)
  2. matplotlib.pyplot.show() ---> 2 plotters (ASAP plotter and matplotlib plotter) are displayed and casapy prompt is paused.
  3. close all plotter windows ---> casapy prompt should be back

Put in Release Notes: No

Module(s): sdplot, asap.plotter

Description:

Fixed a bug in asapplotter with Tk backend which caused scripts and python shells
freeze after the initial invocation of matplotlib.pyplot.show() (known as pl.show() on CASA).
plus minor fixes which handle backend dependencies.
