Plot data from tables via plotter
Requires:

Synopsis

Description

tableplot is a plotting tool for general CASA tables. Table columns can be plotted against each other, and can be combined using TaQL to create expressions for derived quantities, the result of which can then be plotted. Data from more than one table can be accessed and plotted at the same time. Expressions producing arrays result in overlay plots. The default plot style is single-panel, but if an iteration axis is specified, multi-panel plots are supported. Zooming and region-based flagging is possible on single and multi panel plots. A GUI, adapted to a particular kind of table (measurement set) can call the tableplot functions and customize the generated plots. Methods

open	Specify list of tables to operate on.
setgui	Set the GUI on or off. Can be done only once !!
savefig	Save the currently plotted image.
selectdata	Perform a TaQL based subtable selection for subsequent plots.
plotdata	Plot the result of a general TaQL expression.
iterplotstart	Initialize plotting with an iteration axis
replot	Replot all existing panels and layers.
iterplotnext	Start/Continue plotting
iterplotstop	Stop plot iterations.
markregions	Mark a rectangular region to flag
flagdata	Flag Data for selected flag regions
unflagdata	Unset flags for all regions marked using tp.markregions().
locatedata	Print info about data selected using tp.markregions().
clearflags	Clear all flags in the table.
saveflagversion	Save current flags with a version name.
restoreflagversion	Restore flags from a saved flag_version.
deleteflagversion	Delete a saved flag_version.
getflagversionlist	Print out a list of saved flag_versions.
clearplot	Clear a plot.
