After discussing the cntrparm problem on this list, the following script
still doesn't work as expected with the newest Gnuplot CVS:
---- clip ----
set log z
set palette model HSV functions gray, gray, 0.8-0.5*gray
set log cb
set view map
set cntrparam level incremental 5,2,200
splot x**2+y**2+1.0 palette
---- clap ----
Nothing is plotted. The problem is in the "cntrparam level incremental"
definition; Gnuplot recognizes the values as linear increments in
logarithmic axis, which leads in HUGE steps in the actual z-value. The
steps go like (10^5, 10^7, 10^9, ... , 10^200), which is obviously very
I wrote a very small patch so that '5,2,200' delivers tics at
(5,10,20,40,80,160), as should be the case.
