import gr
import sequtils, sugar, math
let x = linRange(-2.0, 2.0, 40)
let y = x.map(x => x^3 + x^2 + x)
plot2(x,y)
discard readLine(stdin)
grm_finalize()
creates the following window:
Note
Why plot2? Well I have created another plot function which does not depend on GRM and they share the same API.
