*** QUESTION: HOW MANY FUNCTIONS THAT CAN BE PLOTTED AT ONCE?

[Pier L. L. <la...@el...>]

dear gnuplot people,=20

sorry to bother with probably a naive question.

I have a problem with gnuplot. I have a program that=20
generates=20
many functions that must be plotted all together in the=20
same plot.=20

An example of the typical script I generate is in attach.

If you plot it, some holes in the plot will appear as if=20
some sections of the domain are not covered.

This for instance happens between 0 and 100.

Then, if you change the script and plot only the section=20
between 0 and 100 the holes disappear.

Basically some functions in the script I put in attach are=20
not plotted.

Is there a limit to the number of functions that gnuplot=20
can plot at once?

What can I do? :)

Thank you!

It is for a paper that I have to submit soon! :))

You're plot a piece-wise continuous funtion of sorts, right?  I'm under 
the impression that gnuplot is plotting exactly what you are telling it 
to.  Look closely at your sections and consider stuff like this (which 
plots nothing):

 cl1841173(x1)=(x1>=1000 && x1<=1000)?-10.1292*1000+x1*10.1268:1/0

It is at least part a matter of how finely you sample along
the x axis.  Try setting
	set sample 10000
before your plot command

No.  Although eventually you might run out of memory to
store them.
