# matplotlib.axis.YTick.set_contains

`YTick.``set_contains`(picker)

  Replace the contains test used by this artist. The new picker should be a callable function which determines whether the artist is hit by the mouse event:

      hit, props = picker(artist, mouseevent)

  If the mouse event is over the artist, return hit = True and props is a dictionary of properties you want returned with the contains test.
