source: trunk/python/flagtoolbar.py@ 2070

Last change on this file since 2070 was 2066, checked in by Kana Sugimoto, 14 years ago

New Development: No

JIRA Issue: Yes (CAS-1306/ATNF-205)

Ready for Test: Yes

Interface Changes: No

What Interface Changed:

Test Programs:

load flagplotter (sdplot with interactive=True in CASA)
press 'region' button, select channel regions.

Put in Release Notes: No

Module(s): sdflag, flagplotter

Description:

Implemented backend dependent plotting method to update rectangle plot,
which indecates the current channel selection, faster with the mouse movement.
Minor fix in a log output.
