\defgroup jkqtplotter_elements Plot Element Classes
\ingroup jkqtplotter_classdoc

This group assembles all classes that represent different elements of a plot (managed by JKQTBasePlotter/JKQTPlotter).
There are these major subgroups:
  - \ref jkqtpbaseplotter_elements contains all non-graph objects, i.e. things like coordinate axes and so on
  - \ref jkqtplotter_concretegraphs contains the actual graph classes
.

\defgroup jkqtpbaseplotter_elements Non-Graph Plot Elements
\ingroup jkqtplotter_elements

This group contains some tool classes that implement basic elements of the plot (coordinate axes, key, ...).
These classes are used by JKQTPlotterBase to output the plot.
