Used for y-axis labels, and if `add_titles` is True also for titles. If not given, integers 1..data.shape[1] are used. ell_kwds : dict, optional UNUSED plot_kwds : dict, optional UNUSED add_titles : bool, optional Whether or not to add titles to each subplot. Default is False. Titles are constructed from `varnames`. keep_ticks : bool, optional If False (default), remove all axis ticks. fig : Matplotlib figure instance, optional If given, this figure is simply returned. Otherwise a new figure is created. Returns ------- fig : Matplotlib figure instance If `fig` is None, the created figure. Otherwise `fig` itself.
