Detailed Description

abstract base class that will hold a single dataset that can be rendered as a line

This class extends PlotData with support for drawing lines, defined by their color, style and width. Getters and setters are provided for each of these properties. Important is that whenever a property is changed, signal_changed() is emitted, which will eventually be picked up by the canvas that will hold the plot
