Plotting Average curve for points in gnuplot

Question

[Current]

I am importing a text file in which the first column has simulation time (0~150) the second column has the delay (0.01~0.02).

1.000000 0.01         


        

Answer 1

Here's some replacement code for the top answer, which makes this also work for 1000+ points and much much faster. Only works in gnuplot 5.2 and later I guess

# number of points in moving average
n = 5000

array A[n]

samples(x) = $0 > (n-1) ? n : int($0+1)
mod(x) = int(x) % n
avg_n(x) = (A[mod($0)+1]=x, (sum [i=1:samples($0)] A[i]) / samples($0))
