+ Convenience method for changing the appearance of ticks and
+ tick labels.
+ Keyword arguments:
+
+ *axis*
+ ['x' | 'y' | 'both'] Axis on which to operate;
+ default is 'both'.
+
+ *reset*
+ [True | False] If *True*, set all parameters to defaults
+ before processing other keyword arguments. Default is
+ *False*.
+
+ *which*
+ ['major' | 'minor' | 'both'] Default is 'major': apply
+ arguments to major ticks only.
+
+ *direction*
+ ['in' | 'out'] Puts ticks inside or outside the axes.
+
+ *length*
+ Tick length in points.
+
+ *width*
+ Tick width in points.
+
+ *color*
+ Tick color; accepts any mpl color spec.
+
+ *pad*
+ Distance in points between tick and label.
+
+ *labelsize*
+ Tick label font size in points or as a string (e.g. 'large').
+
+ *labelcolor*
+ Tick label color; mpl color spec.
+
+ *colors*
+ Changes the tick color and the label color to the same value:
+ mpl color spec.
+
+ *zorder*
+ Tick and label zorder.
+
+ *bottom*, *top*, *left*, *right*
+ Boolean or ['on' | 'off'], controls whether to draw the
+ respective ticks.
+
+ *labelbottom*, *labeltop*, *labelleft*, *labelright*
+ Boolean or ['on' | 'off'], controls whether to draw the
+ respective tick labels.
+
+ Example::
+
+ ax.tick_params(direction='out', length=6, width=2, colors='r')
+
+ 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.
