We next will show how to do a basemap for a log-log plot. We will assume that the raw x data range from 3 to 9613 and y ranges from to . One possibility is
psbasemap -R1/10000/1e20/1e25 -JX9il/6il \ -B2:"Wavelength (m)":/a1pf3:"Power (W)":WS >! plot.ps
(The backslash makes UNIX ignore the carriage return that follows and treat the two lines as one long command).
