Re: [Gnuplot-info] variable defined from reading a file?

[Thomas S. <t.s...@fz...>]

plot in a loop using the 'reload' command and store the mu and sigma values
in variables specific to each sub-plot:

file 'ts.plt':

###############
i=0
f(x,mu,sigma)=exp(-(x-mu)**2/2/sigma**2)/sqrt(2*pi)/sigma
load 'ts.loop'
###############

file 'ts.loop':

###############
if (i==0) \
eval "plot 'ts.dat' using (mu".i."=column(1),sigma".i."=column(2),0/0):(0/0)
every ::".i."::".i." notitle, f(x,mu".i.",sigma".i.")" \
; else \
eval "replot 'ts.dat' using
(mu".i."=column(1),sigma".i."=column(2),0/0):(0/0) every ::".i."::".i."
notitle, f(x,mu".i.",sigma".i.")"

i=i+1
reread
###############

start it with:

load 'ts.plt'
