Parameters
3153+
----------
3154+
left : scalar, optional
3155+
The left xlim (default: None, which leaves the left limit
3156+
unchanged).
3157+
3158+

The right xlim (default: None, which leaves the right limit

3161+
3162+
emit : bool, optional
3163+
Whether to notify observers of limit change (default: True).
3164+
3165+
xlimits : tuple, optional

The left and right xlims may be passed as the tuple
3167+
(`left`, `right`) as the first positional argument (or as

-------
3172+
xlimits : tuple
3173+
Returns the new x-axis view limits as (`left`, `right`).
3174+
3175+
Notes
3176+
-----
3177+
The `left` value may be greater than the `right` value, in which
3178+
case the x-axis values will decrease from left to right.
