Description

Preconfigured setup for data visualisation with Gnuplot.

The visualisation tool gnuplot allows for simple data visualisation in various formats, integrated into a *NIX commandline work environment.

The namespace lib::gnuplot_gen allows to generate diagrams relying on some common layout schemes, which can be customised. Data is passed in as CSV string; the generated Gnuplot script adapts dynamically to the number of data columns given, where the first column always holds the common x-axis values. Additional parameters can be added to the data binding used for script generation; this binding is comprised of key = value settings in a Rec<GenNode> (Lumiera's »ETD« format for structural data)

Todo:

3/2024 this is an initial draft, shaped by the immediate need to visualise measurement data collected while testing the new Scheduler implementation.
