The Charts Definition Language gives the user the possibility to define his own charts on the basis of the CumulusMX infrastructure through the [[ChartsCompiler]]. This article gives the specification of that language.
=== CutilsCharts.def ===
The charts are defined in the definition file (''CutilsCharts.def'' which resides in the ''utils'' directory) which contains one or more chart specifications according to the figure below. All attributes of a plot variable are optional and if not specified have a reasonable default. All white space characters are used as separators so it is easy to make a visually attractive, readable definition file.
The text in the ''CutilsCharts.def'' is case independent, however for clarity [https://en.wikipedia.org/wiki/Camel_case CamelCase] or a variety thereof is advised.
The [[ChartsCompiler]] is obligatory after the introduction of the [[Extra Sensors|ExtraSensors]] module from version 6.5
A standard CutilsCharts.def and a CutilsCharts-example.def are in the distribution. The first for an initial setup, the second to guide the user into the possibilities.
