Last change on this file since 3091 was 2719, checked in by Kana Sugimoto, 12 years ago

New Development: No

JIRA Issue: No

Ready for Test: Yes

Interface Changes: Yes

What Interface Changed: added two new methods, get_gref() and get_gcellval() in plothelper class.

Test Programs: test_sdplot[sdplot_gridTest]

Put in Release Notes: No

Module(s): asapplotter and sdplot

Description:

Added two new methods in plothelper class to get grid center
and spacings of plot grids.

  • get_gref(): returns the reference direction (grid center) of grid (a string)
  • get_gcellval(): returns the absolute increment (in radian) of grid (a double vector)
