I have a question about the axes on log_log plots in PV Wave. Years
ago, I submitted a bug report. It was acknowledged, but it does not
seem to have been fixed, at least up to CL Version 6.01.
The problem occurs in the labels of the axes when one forces the range
to be part (or parts) of a decade. Consider the (real!) data given by
WAVE> print, v
550.000 600.000 650.000 700.000 750.000 800.000
850.000 900.000 950.000 1000.00 1050.00 1100.00
1150.00 1200.00 1250.00 1300.00 1350.00 1400.00
WAVE> print, imax
121.478 155.636 196.968 261.045 342.144 440.244
539.048 679.079 825.724 1033.60 1238.57 1568.95
1825.55 2204.99 2612.35 2980.93 3218.63 3254.11
Now,
WAVE> plot_oo, v, imax
will produce a correct plot. However, the command
WAVE> plot_oo, v, imax, xran = [500,1500], /xsty
will produce a bogus x axis. The plotted points themselves look correctly
placed in the x direction and there is no problem along the y axis, either,
but the x labels are not where they ought to be.
Does anyone know if this has been fixed in later versions?
How does IDL work with this data for xrange = [500, 1500]?
thanks
