Method QCPLayerable

qcustomplot/qcustomplot.cpp:1339–1354

! Creates a new QCPLayerable instance. Since QCPLayerable is an abstract base class, it can't be instantiated directly. Use one of the derived classes. If \a plot is provided, it automatically places itself on the layer named \a targetLayer. If \a targetLayer is an empty string, it places itself on the current layer of the plot (see \ref QCustomPlot::setCurrentLayer). It is

  QCPLayerable subclasses, to guarantee a working destruction hierarchy.
