libraryDependencies += "xyz.devfortress.splot" % "splot-core_2.13" % "0.5.0"It can plot line plots, scatter plots, arbitrary closed polygons, heatmap plots etc.
To try it out type or cut-and-paste following into your Ammonite-REPL
import $ivy.`xyz.devfortress.splot::splot-core:0.5.0`, xyz.devfortress.splot._

def y(t: Double): Double = cos(PI * t + 2) * t

val xy = mkSeq(2, 20, 0.01).map(t => (sin(t)/t, cos(PI * t + 2) * t ))
fig.plot(xy, color = "blue", lw = 2)
fig.add(Label("Parametric curve", 0.18, 7.3, fontSize = 30, color = Color.RED))
fig.scatter(Seq((x(2), y(2))), pt = "o", ps = 10, color = "red")
fig.scatter(Seq((x(20), y(20))), pt = "o", ps = 10, color = "red")
fig.add(Label("start", x = x(2), y = y(2) + 0.8, anchor = Anchor.RIGHT_LOWER, fontSize = 20))
fig.add(Label("end", x = x(20), y = y(20) - 0.5, anchor = Anchor.RIGHT_UPPER, fontSize = 20))
fig.show(900, 600)You should see a window popup with following figure.
