Plot Bunch
Edit pageLast modified: 29 February 2024plotBunch() allows showing a collection of plots on one figure. Each plot in the collection can have an arbitrary location and size. There is no automatic layout inside the bunch.
val cov: Array<DoubleArray> = arrayOf(
doubleArrayOf(1.0, 0.0),
doubleArrayOf(0.0, 1.0)
)
val means: DoubleArray = doubleArrayOf(0.0, 0.0)
val random = JDKRandomGenerator(42)
val xy = MultivariateNormalDistribution(random, means, cov).sample(400)
val xs = xy.map { it[0] }
val ys = xy.map { it[1] }View this data as a scatter plot and as a histogram
plot {
points {
x(xs)
y(ys)
color = Color.GREY
alpha = .4
}
layout {
size = 600 to 200
xAxisLabel = "x"
yAxisLabel = "y"
}
}
plot {
histogram(xs) {
fillColor = Color.named("dark_magenta")
}
layout {
size = 600 to 200
xAxisLabel = "x"
}
}
Combine both plots in one figure
val scaleX = Scale.continuousPos(-3.5..3.5)
plotBunch {
add(plot {
histogram(xs) {
x { scale = scaleX }
fillColor = Color.named("dark_magenta")
}
layout {
size = 600 to 200
xAxisLabel = "x"
}
}, 0, 0)
add(plot {
points {
x(xs) { scale = scaleX }
y(ys)
color = Color.GREY
alpha = .4
}
layout {
size = 600 to 200
xAxisLabel = "x"
yAxisLabel = "y"
}
}, 0, 200)
}
Adjust visuals of the bunch figure
val upperStyle = Style.createCustom {
blankAxes()
axis.text { }
yAxis.title { }
panel.grid.majorYLine {
blank = true
}
}
val lowerStyle = Style.createCustom {
blankAxes()
yAxis.text { }
axis.title { }
}plotBunch {
add(plot {
histogram(xs) {
x { scale = scaleX }
fillColor = Color.named("dark_magenta")
}
layout {
size = 600 to 200
xAxisLabel = "x"
style(upperStyle)
}
}, 0, 0)
add(plot {
points {
x(xs) { scale = scaleX }
y(ys)
color = Color.GREY
alpha = .4
}
layout {
size = 600 to 200
xAxisLabel = "x"
yAxisLabel = "y"
style(lowerStyle)
}
}, 0, 200)
}
Adjust plot sizes
add method has two more (optional) parameters: width and height.
These values will override the plot size earlier defined via size property.
plotBunch {
add(plot {
histogram(xs) {
x { scale = scaleX }
fillColor = Color.named("dark_magenta")
}
layout {
size = 600 to 200
xAxisLabel = "x"
style(upperStyle)
}
}, 0, 0, 600, 100)
add(plot {
points {
x(xs) { scale = scaleX }
y(ys)
color = Color.GREY
alpha = .4
}
layout {
size = 600 to 200
xAxisLabel = "x"
yAxisLabel = "y"
style(lowerStyle)
}
}, 0, 100, 600, 300)
}
