Last change on this file since 2572 was 2538, checked in by Kana Sugimoto, 12 years ago

New Development: No

JIRA Issue: Yes (related to CAS-3749)

Ready for Test: Yes

Interface Changes: Yes

What Interface Changed: added a new method, _alive(), in asaplotbase class

Test Programs: Interactive tests

Put in Release Notes: No

Module(s):

Description:

Added a new method, _alive(), in asaplotbase class. The method return True
if asaplot instance is alive. More complete check compared to 'is_dead' parameter.
asapplotter._assert_plotter method is simplified by calling this function.

Fixed misc bugs found in interactive tests.

set back linewidth = 1 in plots invoked by modules, interactivemask, asapmath, and asapfitter.
interactivemask module: plotter in properly quited at the end.
interactivemask module: avoid error when user close interacive plot window before calling the finalization method, finish_selection().
added definition of a dummy function, quit(), in asaplot class.
