To see the result, command (11) defines the X axis units (here Velocity, but channel number or Frequency may be used). Then commands (12,13) define the plotting limits (in Velocity and Antenna Temperature respectively). Command (14) specifies that the spectrum will be plotted as a histogram, instead of the simpler, but less realistic, segmented line. The PLOT command (15) draws the axes, labels, the spectrum and its title. Each of these operations may be performed separately if needed.
A hardcopy of this plot can be obtained as in command line (16). This creates a file which is automatically sent to a plot spooler. The plot appears on the local system plotter device.
