Common tick options to all cartesian axes

Namespace: options.scales[scaleId].ticks

Name	Type	Default	Description
align	string	'center'	The tick alignment along the axis. Can be 'start', 'center', 'end', or 'inner'. inner alignment means align start for first tick and end for the last tick of horizontal axis
crossAlign	string	'near'	The tick alignment perpendicular to the axis. Can be 'near', 'center', or 'far'. See Tick Alignment
sampleSize	number	ticks.length	The number of ticks to examine when deciding how many labels will fit. Setting a smaller value will be faster, but may be less accurate when there is large variability in label length.
autoSkip	boolean	true	If true, automatically calculates how many labels can be shown and hides labels accordingly. Labels will be rotated up to maxRotation before skipping any. Turn autoSkip off to show all labels no matter what.
autoSkipPadding	number	3	Padding between the ticks on the horizontal axis when autoSkip is enabled.
includeBounds	boolean	true	Should the defined min and max values be presented as ticks even if they are not "nice".
labelOffset	number	0	Distance in pixels to offset the label from the centre point of the tick (in the x-direction for the x-axis, and the y-direction for the y-axis). Note: this can cause labels at the edges to be cropped by the edge of the canvas
maxRotation	number	50	Maximum rotation for tick labels when rotating to condense labels. Note: Rotation doesn't occur until necessary. Note: Only applicable to horizontal scales.
minRotation	number	0	Minimum rotation for tick labels. Note: Only applicable to horizontal scales.
mirror	boolean	false	Flips tick labels around axis, displaying the labels inside the chart instead of outside. Note: Only applicable to vertical scales.
padding	number	0	Padding between the tick label and the axis. When set on a vertical axis, this applies in the horizontal (X) direction. When set on a horizontal axis, this applies in the vertical (Y) direction.
maxTicksLimit	number	11	Maximum number of ticks and gridlines to show.
