matplotlib.axes.Axes.tick_params

Axes.tick_params(axis='both', **kwargs)

Change the appearance of ticks, tick labels, and gridlines.

Tick properties that are not explicitly set using the keyword arguments remain unchanged unless reset is True.

Parameters:

Parameters:	axis{'x', 'y', 'both'}, default: 'both' The axis to which the parameters are applied. which{'major', 'minor', 'both'}, default: 'major' The group of ticks to which the parameters are applied. resetbool, default: False Whether to reset the ticks to defaults before updating them.
Other Parameters:	direction{'in', 'out', 'inout'} Puts ticks inside the axes, outside the axes, or both. lengthfloat Tick length in points. widthfloat Tick width in points. colorcolor Tick color. padfloat Distance in points between tick and label. labelsizefloat or str Tick label font size in points or as a string (e.g., 'large'). labelcolorcolor Tick label color. colorscolor Tick color and label color. zorderfloat Tick and label zorder. bottom, top, left, rightbool Whether to draw the respective ticks. labelbottom, labeltop, labelleft, labelrightbool Whether to draw the respective tick labels. labelrotationfloat Tick label rotation grid_colorcolor Gridline color. grid_alphafloat Transparency of gridlines: 0 (transparent) to 1 (opaque). grid_linewidthfloat Width of gridlines in points. grid_linestylestr Any valid `Line2D` line style spec.

axis{'x', 'y', 'both'}, default: 'both': The axis to which the parameters are applied.
which{'major', 'minor', 'both'}, default: 'major': The group of ticks to which the parameters are applied.
resetbool, default: False: Whether to reset the ticks to defaults before updating them.

Other Parameters:

direction{'in', 'out', 'inout'}: Puts ticks inside the axes, outside the axes, or both.
lengthfloat: Tick length in points.
widthfloat: Tick width in points.
colorcolor: Tick color.
padfloat: Distance in points between tick and label.
labelsizefloat or str: Tick label font size in points or as a string (e.g., 'large').
labelcolorcolor: Tick label color.
colorscolor: Tick color and label color.
zorderfloat: Tick and label zorder.
bottom, top, left, rightbool: Whether to draw the respective ticks.
labelbottom, labeltop, labelleft, labelrightbool: Whether to draw the respective tick labels.
labelrotationfloat: Tick label rotation
grid_colorcolor: Gridline color.
grid_alphafloat: Transparency of gridlines: 0 (transparent) to 1 (opaque).
grid_linewidthfloat: Width of gridlines in points.
grid_linestylestr: Any valid Line2D line style spec.

Examples

ax.tick_params(direction='out', length=6, width=2, colors='r',
               grid_color='r', grid_alpha=0.5)

This will make all major ticks be red, pointing out of the box, and with dimensions 6 points by 2 points. Tick labels will also be red. Gridlines will be red and translucent.
