The Schemannian Reference

Data Virtualization

"Schemannian" supports two functions plot and listplot for plotting and data visualization.

(plot func x-min x-max y-min y-max) → pict?
    func : procedure?
    x-min : real?
    x-max : real?
    y-min : real?
    y-max : real?

(listplot lst x-min x-max y-min y-max) → pict?
    lst : list?
    x-min : real?
    x-max : real?
    y-min : real?
    y-max : real?

For listplot, every element in lst is a list of two numbers (so you can get them by car and cadr), as the x and y coordinate of the plotting point.

For example,

(require "plot.rkt")
(plot cos 0 10 -2 2)

gives you a cosine curve of y = cos(x) in the plotting region 0 < x < 10 and -2 < y < 2.
