title: subplot_grid author: Daniel Jones part: Geometry order: 1011 ...

Draw multiple subplots in a grid orginized by one or two categorial vectors.

Aesthetics

• xgroup (optional): Arrange subplots on the X-axis by categorial data.
• ygroup (optional): Arrange subplots on the Y-axis by categorial data.

One or both of xgroup or ygroup must be bound. If only one, a single column or row of subplots is drawn, if both, a grid.

Arguments

Geom.subplot_grid(elements::Gadfly.ElementOrFunction...)

Unlike most geometries, Geom.subplot_grid is typically passed one or more parameters. The constructor works for the most part like the layer function. Arbitrary plot elements may be passed, while aesthetic bindings are inherited from the parent plot.

Examples

using RDatasets
using Gadfly

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

set_default_plot_size(20cm, 7.5cm)
plot(data("datasets", "OrchardSprays"),
     xgroup="treatment", x="colpos", y="rowpos", color="decrease",
     Geom.subplot_grid(Geom.point))

set_default_plot_size(14cm, 25cm)
plot(data("vcd", "Suicide"), xgroup="sex", ygroup="method", x="age", y="Freq",
     Geom.subplot_grid(Geom.bar))
