  // The fact that the ancillary items are created before trace plots is not a

  // derived classes at the most appropriate moment in the setting up of the
  // widget.

  // All this is only a workaround of a bug in QCustomPlot. See

Destruct this BasePlotWidget instance.

The destruction involves clearing the history, deleting all the axis range history items for x and y axes.

  m_xAxisRangeHistory.clear();

  // Note that the QCustomPlot xxxItem objects are allocated with (this) which
