Graph : VisualElement

This is the base class for all graph elements. It is a point based graph.

Usage

local graph = main:addGraph()
:addSeries("input", " ", colors.green, colors.green, 10)
:addSeries("output", " ", colors.red, colors.red, 10)

basalt.schedule(function()
while true do
graph:addPoint("input", math.random(1,100))
graph:addPoint("output", math.random(1,100))
sleep(2)
end
end)

Properties

Property	Type	Default	Description
