Vertical text baseline of axis tick labels, overriding the default setting for the current axis orientation. One of "alphabetic" (default), "top", "middle", "bottom", "line-top", or "line-bottom". The "line-top" and "line-bottom" values operate similarly to "top" and "bottom", but are calculated relative to the lineHeight rather than fontSize alone.

labelBoundbool, dict, float, ExprRef

Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColorstr, dict, Color, ExprRef, HexColor, ColorName, ConditionalAxisColor, Literal[‘black’, ‘silver’, ‘gray’, ‘white’, ‘maroon’, ‘red’, ‘purple’, ‘fuchsia’, ‘green’, ‘lime’, ‘olive’, ‘yellow’, ‘navy’, ‘blue’, ‘teal’, ‘aqua’, ‘orange’, ‘aliceblue’, ‘antiquewhite’, ‘aquamarine’, ‘azure’, ‘beige’, ‘bisque’, ‘blanchedalmond’, ‘blueviolet’, ‘brown’, ‘burlywood’, ‘cadetblue’, ‘chartreuse’, ‘chocolate’, ‘coral’, ‘cornflowerblue’, ‘cornsilk’, ‘crimson’, ‘cyan’, ‘darkblue’, ‘darkcyan’, ‘darkgoldenrod’, ‘darkgray’, ‘darkgreen’, ‘darkgrey’, ‘darkkhaki’, ‘darkmagenta’, ‘darkolivegreen’, ‘darkorange’, ‘darkorchid’, ‘darkred’, ‘darksalmon’, ‘darkseagreen’, ‘darkslateblue’, ‘darkslategray’, ‘darkslategrey’, ‘darkturquoise’, ‘darkviolet’, ‘deeppink’, ‘deepskyblue’, ‘dimgray’, ‘dimgrey’, ‘dodgerblue’, ‘firebrick’, ‘floralwhite’, ‘forestgreen’, ‘gainsboro’, ‘ghostwhite’, ‘gold’, ‘goldenrod’, ‘greenyellow’, ‘grey’, ‘honeydew’, ‘hotpink’, ‘indianred’, ‘indigo’, ‘ivory’, ‘khaki’, ‘lavender’, ‘lavenderblush’, ‘lawngreen’, ‘lemonchiffon’, ‘lightblue’, ‘lightcoral’, ‘lightcyan’, ‘lightgoldenrodyellow’, ‘lightgray’, ‘lightgreen’, ‘lightgrey’, ‘lightpink’, ‘lightsalmon’, ‘lightseagreen’, ‘lightskyblue’, ‘lightslategray’, ‘lightslategrey’, ‘lightsteelblue’, ‘lightyellow’, ‘limegreen’, ‘linen’, ‘magenta’, ‘mediumaquamarine’, ‘mediumblue’, ‘mediumorchid’, ‘mediumpurple’, ‘mediumseagreen’, ‘mediumslateblue’, ‘mediumspringgreen’, ‘mediumturquoise’, ‘mediumvioletred’, ‘midnightblue’, ‘mintcream’, ‘mistyrose’, ‘moccasin’, ‘navajowhite’, ‘oldlace’, ‘olivedrab’, ‘orangered’, ‘orchid’, ‘palegoldenrod’, ‘palegreen’, ‘paleturquoise’, ‘palevioletred’, ‘papayawhip’, ‘peachpuff’, ‘peru’, ‘pink’, ‘plum’, ‘powderblue’, ‘rosybrown’, ‘royalblue’, ‘saddlebrown’, ‘salmon’, ‘sandybrown’, ‘seagreen’, ‘seashell’, ‘sienna’, ‘skyblue’, ‘slateblue’, ‘slategray’, ‘slategrey’, ‘snow’, ‘springgreen’, ‘steelblue’, ‘tan’, ‘thistle’, ‘tomato’, ‘turquoise’, ‘violet’, ‘wheat’, ‘whitesmoke’, ‘yellowgreen’, ‘rebeccapurple’], None

The color of the tick label, can be in hex color code or regular color name.

labelExprstr

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the axis’s backing datum object.

labelFlushbool, float

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffsetdict, float, ExprRef

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

Default value: 0.

labelFontstr, dict, ExprRef, ConditionalAxisString

The font of the tick label.

labelFontSizedict, float, ExprRef, ConditionalAxisNumber

The font size of the label, in pixels.

Default value: 0

labelOpacitydict, float, ExprRef, ConditionalAxisNumber

The opacity of the labels.

labelOverlapbool, dict, ExprRef, LabelOverlap, Literal[‘greedy’, ‘parity’]

The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

labelPaddingdict, float, ExprRef, ConditionalAxisNumber

The padding in pixels between labels and ticks.

Default value: 2

labelSeparationdict, float, ExprRef

Default value: derived from the axis config’s offset (0 by default)

orientdict, ExprRef, AxisOrient, Literal[‘top’, ‘bottom’, ‘left’, ‘right’]

The orientation of the axis. One of "top", "bottom", "left" or "right". The orientation can be used to further specialize the axis type (e.g., a y-axis oriented towards the right edge of the chart).

Default value: "bottom" for x-axes and "left" for y-axes.

positiondict, float, ExprRef

The anchor position of the axis in pixels. For x-axes with top or bottom orientation, this sets the axis group x coordinate. For y-axes with left or right orientation, this sets the axis group y coordinate.

Default value: 0

stylestr, Sequence[str]

A string or array of strings indicating the name of custom styles to apply to the axis. A style is a named collection of axis property defined within the style configuration. If style is an array, later styles will override earlier styles.

Default value: (none) Note: Any specified style will augment the default style. For example, an x-axis mark with "style": "foo" will use config.axisX and config.style.foo (the specified style "foo" has higher precedence).

tickBanddict, ExprRef, Literal[‘center’, ‘extent’]

For band scales, indicates if ticks and grid lines should be placed at the "center" of a band (default) or at the band ``”extent”``s to indicate intervals

Default value: "gray"

tickCountdict, float, ExprRef, TimeInterval, TimeIntervalStep, Literal[‘millisecond’, ‘second’, ‘minute’, ‘hour’, ‘day’, ‘week’, ‘month’, ‘year’]

A desired number of ticks, for axes visualizing quantitative scales. The resulting number may be different so that values are “nice” (multiples of 2, 5, 10) and lie within the underlying scale’s range.

For scales of type "time" or "utc", the tick count can instead be a time interval specifier. Legal string values are "millisecond", "second", "minute", "hour", "day", "week", "month", and "year". Alternatively, an object-valued interval specifier of the form {"interval": "month", "step": 3} includes a desired number of interval steps. Here, ticks are generated for each quarter (Jan, Apr, Jul, Oct) boundary.

Default value: Determine using a formula ceil(width/40) for x and ceil(height/40) for y.

The width, in pixels, of ticks.

Default value: 1

ticksbool

Boolean value that determines whether the axis should include ticks.

Default value: true

titlestr, Text, Sequence[str], None

A title for the field. If null, the title will be removed.

Default value: derived from the field’s name and transformation function (aggregate, bin and timeUnit). If the field has an aggregate function, the function is displayed as part of the title (e.g., "Sum of Profit"). If the field is binned or has a time unit applied, the applied function is shown in parentheses (e.g., "Profit (binned)", "Transaction Date (year-month)"). Otherwise, the title is simply the field name.

Notes:

1) You can customize the default field title format by providing the fieldTitle property in the config or fieldTitle function via the compile function’s options.

2) If both field definition’s title and axis, header, or legend title are defined, axis/header/legend title will be used.
