New Development: No

JIRA Issue: Yes (CAS-1801, CAS-2064)

Ready to Release: Yes

Interface Changes: Yes

What Interface Changed:
Three methods, print_headder(), set_panellayout() and _reset_panellayout()
are added to the class asapplotter.
A parameter layout (list) is added to set_layout() in asaplotbase class.

Test Programs: run sdplot with header & plotstyle=True + layout parameter set.

Put in Release Notes: Yes

Module(s): sdplot() task.

Description:

1. asapplotter.print_header(plot=True, fontsize=9, logger=False, selstr=, extrastr=): prints scantable header on the plot and/or logger (see help doc for parameter details). Note that the header information will not overlayed to the plot by plotazel() and plotpointing().
2. set_panellayout(layout=[],refresh=True): sets the layout of subplots. layout is a list of subplots layout in figure coordinate (0-1) in order of [left, bottom, right, top, horizontal space btw panels, vertical space btw panels]
3. _reset_panellayout(): resets the layout of subplots to matplotlib rc value.
4. a member variable 'asapplotter._panellayout' (list) is specified to store layout values.
