Hi Ray,
about a log plotting option ---
> If someone wants to design the interface, I can help implement it.
Well, how about this.
(1) logx and logy are boolean plot_options which indicate
logarithmic transform of the x and y axes respectively.
(2) redefine function to plot as f(exp(x)), log(f(x)), or log(f(exp(x)))
(hope I got that right)
(3a) if plot type supports logarithmic transform:
(at present I believe this is only gnuplot and mgnuplot)
emit plot package option to turn on log transform
(3b) otherwise: somehow indicate the axes have been transformed
maybe change axis label? seems problematic.
maybe print a message on the console? not sure.
I'm sure this isn't the end of the story but I hope this is enough
to get us pointed in the right direction.
Thanks for your help,
Robert Dodier
