WHAT IS IT?

This code example shows you how to plot a "smoothed" version of a jagged line. When you run the model, the black line is the original line, and the blue line is the smoothed version.

The amount of smoothing is controlled by the SMOOTHNESS slider.

The black line is generated by doing a one-dimensional random walk.

THINGS TO NOTICE

The very simple method used to do smoothing causes the smoothed line to lag a bit behind the original line, that is, it appear shifted to the right.

to go
  ;; the variable N does a random walk
  set n n + one-of [-1 0 1]

  ;; Here's where we calculate the smoothed version of N.
  ;; This one line is the heart of the whole example.
  set smoothed smoothness * smoothed + (1 - smoothness) * n
