[Gnuplot-info] Problem plotting several data files with lines

[Giacomo M. <gia...@em...>]

Hi everyone,
I've a problem trying to plot several data files with lines, no  
matter of the terminal. I've to plot some curves from data files with  
a command  like:
 >plot  "r0_d0.dat" ls 1 ti "z = 0" with lines,\
 > "r1_d0.dat" ls 2 ti "z = R_{max}/2" with lines,\
 > "r2_d0.dat" ls 3 ti "z = R_{max}/4" with lines

Only problem is that when I look at the output it shows only the  
first curve, the key, the labels etc. but nothing about the 2nd and  
3rd curve. Note that is I choose to plot the 2nd curve with points  
and 3rd with linespoints this work... And note that if I try to plot  
something like
 >plot  sin(x) ls 1 ti "z = 0" with lines,\
 > cos(x) ls 2 ti "z = R_{max}/2" with lines,\
 > cos(x)*cos(x) ls 3 ti "z = R_{max}/4" with lines
it works correctly.
What could it be and what could I do?

Thanks in advance,
Giacomo
