Method registerPlottable

src/qt/qcustomplot.cpp:15433–15453

! \internal Registers the specified plottable with this QCustomPlot and, if \ref setAutoAddPlottableToLegend is enabled, adds it to the legend (QCustomPlot::legend). QCustomPlot takes ownership of the plottable. Returns true on success, i.e. when \a plottable isn't already in this plot and the parent plot of \a plottable is this QCustomPlot. This method is called automatically

  This method is called automatically in the QCPAbstractPlottable base class constructor.
