Draw lines between points in the order they appear in the data. This is Geom.line(preserve_order=true).
x: X-axis position.y: Y-axis position.color(optional): Group categorically by color.

Here's a random walk in 2D:
n = 500
srand(1234)
xjumps = rand(n)-.5
yjumps = rand(n)-.5
plot(x=cumsum(xjumps),y=cumsum(yjumps),Geom.path())Here's a spiral:
t = [0:0.2:8pi]
plot(x=t.*cos(t), y=t.*sin(t), Geom.path)
