Get or set the current tick locations and labels of the y-axis.

Pass no arguments to return the current values without modifying them.

ticksarray-like, optional

The list of ytick locations. Passing an empty list removes all yticks.

labelsarray-like, optional

The list of ytick locations.


The list of ylabel Text objects.


Calling this function with no arguments (e.g. yticks()) is the pyplot equivalent of calling get_yticks and get_yticklabels on the current axes. Calling this function with arguments is the pyplot equivalent of calling set_yticks and set_yticklabels on the current axes.


>>> locs, labels = yticks()  # Get the current locations and labels.
>>> yticks(np.arange(0, 1, step=0.2))  # Set label locations.
>>> yticks(np.arange(3), ['Tom', 'Dick', 'Sue'])  # Set text labels.
>>> yticks([0, 1, 2], ['January', 'February', 'March'],
...        rotation=45)  # Set text labels and properties.
>>> yticks([])  # Disable yticks.
