Last change on this file since 2829 was 2603, checked in by Kana Sugimoto, 12 years ago

New Development: No

JIRA Issue: No (bug fixes and a minor improvement)

Ready for Test: Yes

Interface Changes: No

What Interface Changed:

Test Programs: interactive test needed.

Put in Release Notes: No

Module(s): asapplotter, flagplotter, and sdplot (CASA)

Description:

Fixed bugs in asapplotter and flagplotter which prevented users from exiting
from notation mode, when the other buttons in the additional toolbar is not active.
Consintently use 'self._data' in asapplotter.plotgrid() instead of 'scan'.
