[Gnuplot-info] question on "parametric" data style

[Dr. I. D. J. <die...@t-...>]

Dear listmembers,
I have a function (polar diagram) covering many decades of values. I would 
like to have a constant number of values per decade rather than one with 
constant spacing (configured via "set samples VALUE")

I helped myself by creating a file "sourcefile" containing a correspondingly 
configured set of values and using those for my plot.

I. e. I have two functions RE(x) and IM(x), and rather than performing a

set parametric
set trange [0.01:1000000]
plot RE(t),IM(t)

I did a

plot "sourcefile" using RE($1):IM($1)

where "sourcefile" contains a set of values like

0.01,0.02 ...0.1,0.2, say 10 per decade.

This works fine for me but seems somewhat much effort. Is there a more 
"intelligent" way to tell gnuplot to use I. e. a constant number of values per 
decade in parametric mode? Otherwise I have to increase the number of samples 
(nearly ..) beyond all bounds what increases the computation time drastically.

I could not find a corresponding hint neither in "help set samples" nor in 
"help set parametric"

Thank you very much for your efforts,
take care

if you really want to see the pictures above - use some font
with constant spacing like courier! :-)
