JKQTPlotter (and JKQTBasePlotter) offer a styling system, which allows to easily define and transfer plot styling from one object to another.
The system is based on a hirarchy of structs, which summarize properties, describing how a plot looks in general. The classes contained in this system are:
  - JKQTPlotterStyle for JKQTPlotter: Defines e.g. basic user-interactions, the display options of the toolbar
  - JKQTBasePlotterStyle for JKQTBasePlotter defines the appearance of the plot itself (colors, axis properties, key properties, default graph colors/styles, ...), contains JKQTPCoordinateAxisStyle instances to configrue the plot's coordinate axes
  - JKQTPCoordinateAxisStyle for JKQTPCoordinateAxis defines the appearance of a coordinate axis (colors, axis properties, ...)
  - JKQTPKeyStyle for the style of the key/legend in a JKQTBasePlotterStyle
.

In addition there are static methods that allow to manage a system-wide (actually program-instance wide) style that is applied to any new instance of JKQTPlotter and JKQTBasePlotter on construction:
  - JKQTPGetSystemDefaultStyle() / JKQTPSetSystemDefaultStyle() allows to access the central instace of JKQTPlotterStyle (mainly properties/style of the GUI-parts and user-action bindings)
  - JKQTPGetSystemDefaultBaseStyle() / JKQTPSetSystemDefaultBaseStyle() accesses the central instance of JKQTBasePlotterStyle (styles the actual plot/graphs with colors, axes styles, ...)
.

You can e.g. use these general methods to alter the styles for all JKQTPlotter instances, created in the future:
\code{.cpp}
    // load the system-wide default settings from an INI-file:
    QSettings plotSettings("JKQTPlotterSettings.ini", QSettings::IniFormat);;
    JKQTPGetSystemDefaultStyle().loadSettings(plotSettings);
    JKQTPGetSystemDefaultBaseStyle().loadSettings(plotSettings);

    // alter a system-wide default setting by hand (here: set color of zooming rect to red)
    JKQTPGetSystemDefaultStyle().userActionColor=QColor("red");
\endcode

Several pre-made styles are available in the JKQTPlotter repository (<a href="https://github.com/jkriege2/JKQtPlotter/tree/master/lib/jkqtplotter/resources/styles/">https://github.com/jkriege2/JKQtPlotter/tree/master/lib/jkqtplotter/resources/styles/</a>). 
These are also linked into the JKQTPlotter library as Qt ressource into the subdirectory \c :/JKQTPlotter/styles/ . You can use them as follows:

\code{.cpp}
	QSettings plotSettings(":/JKQTPlotter/styles/blackandwhite.ini", QSettings::IniFormat);;
    JKQTPGetSystemDefaultStyle().loadSettings(plotSettings);
    JKQTPGetSystemDefaultBaseStyle().loadSettings(plotSettings);
\endcode
