Re: [Gnuplot-info] Animated plot

[Nunzio L. <nun...@gm...>]

Hi think I've found the solution, something like

created a file "command.gp":

set parametric
plot "$0" using 1:(a=column(1),b=column(2),NaN) every ::count::count
notitle, cos(t)+a,sin(t)+b,"$0" u 1:2 every ::::count w lines
count = count+1
if (count<1000) reread


and then in gnuplot command-line:

count=0
call 'command.gp' 'datafile.dat'

Now, the "if. ..." line presumes the number of datapoints is fixed (i.e.
1000 in this case). Is there a way to change this into "reread until
End-of-File is reached"??

Regards,

NL.
