A plotter/interactive flagger for visibility data.
Task for plotting and interacting with visibility data. A variety
of axes choices (including data column) along with MS selection and
averaging options are provided for data selection. Flag extension
parameters are also available for flagging operations in the plotter.
All of the provided parameters can also be set using the GUI once
the application has been launched. Additional and more specific
operations are available through the GUI and/or through the plotms
tool (pm).
Keyword arguments:

default: ''
xaxis, yaxis -- what to plot on the two axes
default: '' (defaults are xaxis='time',
yaxis='amp' on first execution;
thereafter the most recent
settings are used)

on "Measurement Set selection syntax" for more
tips on using data selection parameters in CASA)

NB: For explicit selections, use a single ampersand (&) to
select only cross-correlations among the specified antennas,
double ampersands (&&) to select cross- and
auto-correlations among the specified antennas, and
triple ampersands (&&&) to select only
auto-correlations. E.g.:
antenna='*&'; selects all cross-correlation baseline
(excludes all auto-correlations)
antenna='*&&&'; selects all auto-correlation baselines
(excludes all cross-correlations)
antenna='1&&1,2,3'; selects baselines 1-1 (auto), 1-2,1-3 (cross)
antenna='VA05&&&'; selects the VA05 autocorrelation
