Discouraged

These methods should be used together with care, calling set_ticks to specify the desired tick locations before calling set_ticklabels to specify a matching series of labels. Calling set_ticks makes a FixedLocator; it's list of locations is then used by set_ticklabels to make an appropriate FuncFormatter.

`Axis.set_ticks`	Set this Axis' tick locations and optionally labels.
`Axis.set_ticklabels`	Set the text values of the tick labels.

`Tick` objects

classmatplotlib.axis.Tick(axes, loc, *, size=None, width=None, color=None, tickdir=None, pad=None, labelsize=None, labelcolor=None, zorder=None, gridOn=None, tick1On=True, tick2On=True, label1On=True, label2On=False, major=True, labelrotation=0, grid_color=None, grid_linestyle=None, grid_linewidth=None, grid_alpha=None, **kw)[source]

Abstract base class for the axis ticks, grid lines and labels.

Ticks mark a position on an Axis. They contain two lines as markers and two labels; one each for the bottom and top positions (in case of an XAxis) or for the left and right positions (in case of a YAxis).

Attributes

tick1lineLine2D: The left/bottom tick marker.
tick2lineLine2D: The right/top tick marker.
gridlineLine2D: The grid line associated with the label position.
label1Text: The left/bottom tick label.
label2Text: The right/top tick label.

bbox is the Bound2D bounding box in display coords of the Axes loc is the tick location in data coords size is the tick size in points

classmatplotlib.axis.XTick(*args, **kwargs)[source]
