I plotted curves by fitting some existing points using gnuplot.
like:
f1(x)=a1/(x**b1)+c1
fit f1(x) "41a091_input.txt" u 1:2 via a1,b1,c1
plot f1(x) with line lt 1 lw 4 lc rgb "blue" notitle,
'41a091_input.txt' using 1:2:3 with yerrorbars lw 2.2 lc rgb "blue" title "∑41a(091)"
My question is :
HOW TO GET DATA from any point on this curve?
Like when x=50?
Thank you so much!

this appears tlo be a gnuplot question rather than a tex one, so is probably off topic here.
