title: line author: Daniel Jones part: Geometry order: 1007 ...

Aesthetics

  • x: X-axis position.
  • y: Y-axis position.
  • color (optional): Group categorically by color.

Arguments

  • preserve_order: Default behavior for Geom.line is to draw lines between points in order along the x-axis. If this option is true, lines will be drawn between points in the order they appear in the data. Geom.path() is Geom.line(preserve_order=true).

Examples

using RDatasets
using Gadfly

Gadfly.prepare_display()
Gadfly.set_default_plot_size(14cm, 8cm)

plot(dataset("lattice", "melanoma"), x="Year", y="Incidence", Geom.line)
plot(dataset("Zelig", "approval"), x="Month",  y="Approve", color="Year", Geom.line)
