msplot.iterplotstart - Function

1.3.3 Plot the first set of iterative plots.

Description

Begin a series of plots using subtables constructed via an iteration axes, which is set in either the mp.plot or mp.plotxy methods. Use iterplotnext() to step through. Multi-panel plots as well as overplots are supported with this function. Overplots have a restriction in that both plots must have the same axies.

Only forward step through is allowed.

Arguments


Inputs

Returns
bool

Example

# create a msplot tool, select the data with field name 3C273 for plot,
# and initialize a plot of Amplitude vs UV distance for
# channel 1 and stokes 1, iterating over Antenna1, and creating
# two plot panels per iteration page.
  mp.open( msname=[’./data/3C273XC1.ms’]);
  plotoptions.nxpanels := 1;
  plotoptions.nypanels := 2;
  plotoptions.windowsize := 6;
  plotoptions.aspectratio := 1.2;
  plotoptions.fontsize := 14.0;
  mp.setdata( fieldNames=[’3C273’] );
  labels := [’Amplitude vs UVdist (iterating over Antenna1)’,’uvdist’,’amplitude’];
  mp.plotxy( x=’SQRT(SUMSQUARE(UVW[1:2]))’ y=’AMPLITUDE(DATA[1,1])’, iteration=’ANTENNA1’ );
  mp.iterplotstart();
To iterate over baseline, for stokes 1, channel 1.
  plotopts.nxpanels := 1;
  plotopts.nypanels := 4;
  labels := [’Amplitude vs UVdist (iterating over Baseline)’,’uvdist’,’amplitude’];
  iteraxes := [’ANTENNA1’,’ANTENNA2’];
  mp.plotxy( x=[’SQRT(SUMSQUARE(UVW[1:2]))’ y=’AMPLITUDE(DATA[1,1])’], iteration=iteraxes )
  mp.iterplotstart();
