Description:
 def _update_plot(self, _):
 """Callback to redraw the plot to reflect the new parameter values."""

        # Since all sliders call this same callback without saying who they are
        # I need to update the values for all parameters. This can be
        # circumvented by creating a seperate callback function for each
        # parameter.

            param.value = self._sliders[param].val
