hline! / vline!

Arguments:

v::VegaVisualization
value::Real = 0
strokeWidth::Real = 1.5
stroke::AbstractString = "#000"
strokeDash::Real = 0

This function mutates :VegaVisualization, adding a horizontal/vertical line at a specified location.

Default Chart

using Vega

x = [0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
y = [28, 43, 81, 19, 52, 24, 87, 17, 68, 49, 55, 91, 53, 87, 48, 49, 66, 27, 16, 15]
g = [0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1]

a = areaplot(x = x, y = y, group = g, stacked = true)

With horizontal lines

hline!(a, value = 60.25, strokeDash = 3)
hline!(a, value = 80, strokeDash = 5)
