.. py:class:: DateAxisItem(*args, **kwargs)

   Bases: :py:obj:`pyqtgraph.AxisItem`


   A tool that provides a date-time aware axis. It is implemented as an
   AxisItem that interpretes positions as unix timestamps (i.e. seconds
   since 1970).
   The labels and the tick positions are dynamically adjusted depending
   on the range.
   It provides a  :meth:`attachToPlotItem` method to add it to a given
   PlotItem


   .. py:attribute:: _pxLabelWidth
      :value: 80



   .. py:attribute:: _oldAxis
      :value: None



   .. py:method:: date_from_timestamp(timestamp)
      :staticmethod:



   .. py:method:: tickValues(minVal, maxVal, size)

      Reimplemented from PlotItem to adjust to the range and to force
      the ticks at "round" positions in the context of time units instead of
      rounding in a decimal base



   .. py:method:: tickStrings(values, scale, spacing)

      Reimplemented from PlotItem to adjust to the range



   .. py:method:: attachToPlotItem(plotItem)

      Add this axis to the given PlotItem
      :param plotItem: (PlotItem)



   .. py:method:: detachFromPlotItem()
      :abstractmethod:


      Remove this axis from its attached PlotItem
