Property	Type	Default	Description

timechart

Datetime x axis and numeric y axis.

Property	Type	Default	Description
thresholds	array of threshold rules	automatic	Color values strictly above or below a numeric threshold. Each rule has value, direction (above/below), color (hex), and optional series (exact label; stat: column). Later matching rules take priority. Values use data units (timespans: milliseconds).
showThresholds	boolean	true	Draw labeled dashed threshold lines within the visible numeric axis range. Conditional coloring remains active when lines are hidden.
title	string	automatic	Title displayed above the chart.
legend	boolean	automatic	Automatic: show for one to nine series.
legendPosition	string	"bottom"	Placement of the legend. Values: "top", "bottom", "left", "right".
theme	string	automatic	Override the application theme. Values: "light", "dark".
xUnit	string	automatic	Format numeric tick labels; automatic uses the column type. Values: "bytes", "decbytes", "bytesps", "bits", "celsius", "fahrenheit", "kelvin", "seconds", "milliseconds", "microseconds", "percent", "percentunit", "none".
