xlim! / ylim!

Arguments:

v::VegaVisualization
min::Real = 0
max::Real = 1000
reverse::Bool = false
round::Bool = false
_type::AbstractString = ""
exponent::Real = 0.3

This function mutates :VegaVisualization, modifying the properties of the scales underlying the axes.

Note that for the exponent keyword, it is only in effect if _type is set to "pow". The default value for "pow" of 0.3 is arbitrary, chosen so that setting _type to "pow" actually does something (the d3/vega default = 1, which is an identity transformation).

Default Axis limits

using Vega

x = [1:100; 1:100]
y = [[1:100] + randn(100); 3.0 + 1.5 * [1:100] + randn(100)]
group = [[1 for i in 1:100]; [2 for i in 1:100]]

v = lineplot(x = x, y = y, group = group)

Modified Axis limits

xlim!(v, min=0, max=200)
ylim!(v, min=0, max=200)

Log Scale (Y-axis)

x = [1:100; 1:100]
y = [[1:100] + randn(100); 3.0 + 1.5 * [1:100] + randn(100)]
group = [[1 for i in 1:100]; [2 for i in 1:100]]

v = lineplot(x = x, y = y, group = group)
ylim!(v, _type = "log")

sqrt Scale (Y-axis)

x = [1:100; 1:100]
y = [[1:100] + randn(100); 3.0 + 1.5 * [1:100] + randn(100)]
group = [[1 for i in 1:100]; [2 for i in 1:100]]

v = lineplot(x = x, y = y, group = group)
ylim!(v, _type = "sqrt")

Power Scale (Y-axis, default exponent = 0.3)

x = [1:100; 1:100]
y = [[1:100] + randn(100); 3.0 + 1.5 * [1:100] + randn(100)]
group = [[1 for i in 1:100]; [2 for i in 1:100]]

v = lineplot(x = x, y = y, group = group)
ylim!(v, _type = "pow")
