Scantable spectra can be plotted at any time. An asapplotter object is used for plotting, meaning multiple plot windows can be active at the same time. On start up a default asapplotter object is created called ``plotter''. This would normally be used for standard plotting.
The plotter, optionally, will run in a multipanel mode and contain multiple plots per panel. The user must tell the plotter how they want the data distributed. This is done using the set_mode function. The default can be set in the users .asaprc file. The units (and frame etc) of the abscissa will be whatever has previously been set by set_unit, set_freqframe etc.
Typical plotter usage would be:
ASAP> scans.set_unit('km/s')
ASAP> plotter.set_mode(stacking='p',panelling='t')
ASAP> plotter.plot(scans)
This will plot multiple polarisation within each plot panel and each scan row in a separate panel.
Other possibilities include:
# Plot multiple IFs per panel
ASAP> plotter.set_mode(stacking='i',panelling='t')
# Plot multiple beams per panel
ASAP> plotter.set_mode(stacking='b',panelling='t')
# Plot one IF per panel, time stacked
ASAP> plotter.set_mode('t', 'i')
# Plot each scan in a seperate panel
ASAP> plotter.set_mode('t', 's')
