The plotter can plot up to 25 panels and stacked spectra per panel. If you have data larger than this (or for your own sanity) you need to select a subset of this data. This is particularly true for multibeam or multi IF data. The plotter set_cursor function is used to select a subset of the data. The arguments row, beam and IF all accept a vector of indices corresponding to row, beam or IF selection. Only the selected data will be plotted. To select on polarisation, see section 11.2.
Examples:
# Select second IF ASAP> plotter.set_cursor(IF=[1]) # Select first 4 beams ASAP> plotter.set_cursor(beam=[0,1,2,3]) # Select a few rows ASAP> plotter.set_cursor(row=[2,4,6,10]) # Multiple selection ASAP> plotter.set_cursor(IF=[1], beam=[0,2], row=range(10))
Note that the plotter cursor selection is independent of the scantable cursor.
