Radar Charts Only: The scaleV object is similar to the scaleY object on x/y-axis charts. (The scaleK object is the radar chart’s scaleX equivalent.) Vertically oriented, it is called the value scale and generally displays quantitative values. Refer to the Radar Charts Tutorial for more information.

Attribute	Type	Description
blended	Boolean	To 'blend' or 'stick' secondary scales to the primary one. Use with the 'placement' attribute (set the value to 'default') and 'offset-start' and 'offset-end' attributes. Default Value: false Introduced in: v2.3.0
borderRadius border-radius	Number	Sets the object's border radius for rounded corners. Larger values create rounder corners, while smaller values create sharper corners. A single value will affect all 4 corners; multiple values will have separate effects on each corner, with the first value affecting the top-left corner, the second value affecting the top-right corner, and so on, in a clockwise direction. A negative value will cut a corner off without rounding. Default Value: 0
borderRadiusBottomLeft border-radius-bottom-left	Number	Sets the object's bottom-left border radius for rounded corners. Larger values create rounder corners, while smaller values create sharper corners. A negative value will cut a corner off without rounding. Default Value: 0
borderRadiusBottomRight border-radius-bottom-right	Number	Sets the object's bottom-right border radius for rounded corners. Larger values create rounder corners, while smaller values create sharper corners. A negative value will cut a corner off without rounding. Default Value: 0
borderRadiusTopLeft border-radius-top-left	Number	Sets the object's top-left border radius for rounded corners. Larger values create rounder corners, while smaller values create sharper corners. A negative value will cut a corner off without rounding. Default Value: 0
borderRadiusTopRight border-radius-top-right	Number	Sets the object's top-right border radius for rounded corners. Larger values create rounder corners, while smaller values create sharper corners. A negative value will cut a corner off without rounding. Default Value: 0
class	String	Sets a class value on the object. Default Value: null
dataN data-n	Any	Prefix attribute or array using "data-" to define a custom token.
decimals	Number	Sets the number of decimal places displayed for each value. Default Value: -1 Chart types: Gauge
decimalsSeparator decimals-separator	String	Sets the separator to be used in place of the default decimal point. Any string or character can be used to replace the decimal. Default Value: '.' Chart types: Gauge
defaultValue default-value	String	Sets the default value token values to display until the value is available. Default Value: null Chart types: Gauge
exponent	Boolean	Sets whether the scale values will be displayed in scientific notation. Particularly useful when dealing with large numbers. Default Value: false Chart types: Gauge
exponentDecimals exponent-decimals	Number	Sets the number of decimals that will be displayed when using scientific notation. Use with the 'exponent' attribute. Default Value: 2 Chart types: Gauge
format	String	To format the appearance of the scale values. Use with the %scale-value (%v) token. Default Value: null Chart types: Gauge
guide	Object	Used to style the lines and backgrounds behind the plotted data. Default Value: null
id	String	Sets the id of the object. Default Value: ''
item	Object, String	Sets the id or style of the item. Sets the item id of the map on which the object/shape is being added (ScaleItem,String). For scales, styles the individual scale labels (ScaleItem). Default Value: ''
itemsOverlap items-overlap	Boolean	To force all of the scale items to display. It is generally used with the 'max-items' attribute. Default Value: false
logBase log-base	Number	Logarithmic Scales only: To set the base value, which defaults to Math.E (Euler's number, the base of natural logarithms). Default Value: 10
master	String	Sets a master scale. The current scale will always be in sync with it's master scale. Default Value: ''
max-value-factor	Boolean	Ratio from (max-min) interval which will be added to the max value. Default Value: true
maxDecimals max-decimals	Number	Sets the max number of decimals that will be used to format the values. Default Value: -1 Chart types: Gauge
maxItems max-items	Number	Sets the maximum number of items displayed. Chart types: Gauge
maxTicks max-ticks	Number	Sets the maximum number of ticks to display on the scale. Chart types: Gauge
maxValue max-value	Number, String	Sets the maximum scale value. Accepted Values: ['auto']
mediaRules media-rules	Array.<Object>	Configure media rules.
min-value-factor	Boolean	Ratio from (max-min) interval which will be subtracted to the min value. Default Value: true
minValue min-value	Number, String	Sets the minimum scale value. Accepted Values: ['auto'] Default Value: -1
multiplier	Boolean	Enables abbreviating large numbers with short units, such as K, M, B, etc.. Default Value: null
negation	String	This attribute will determine how negative values are handled. When using "format":"$%v" setting "negation":"currency" will move the - symbol to the outside of the $ sign. When using "negation" within the "plot": { } object you will see changes in things such as tooltips or anywhere else series data is used to populate values. You need to set "negation" in things such as "scale-y": { } separately. Accepted Values: ['standard', 'currency'] Default Value: 'standard'
normalize	Boolean	Applies roundings to scale boundaries in order to get nicer min/max/step values. Default Value: true Chart types: Gauge
offset	Number	Sets an offset at the start and end of the plotted data. This will cause the data to appear as if it were 'squeezed'. Default Value: 0
offsetEnd offset-end	Number	Sets an offset from the end of the plotted data. This will cause the data to appear as if it were 'squeezed' from the right side. Default Value: 0
offsetStart offset-start	Number	Sets an offset at the start of the plotted data. This will cause the data to appear as if it were 'squeezed' from the left side. Default Value: 0
offsetX offset-x	Number	Sets an x-offset to apply when positioning the object.
offsetY offset-y	Number	Sets an y-offset to apply when positioning the object.
padding	Number	Sets the object's padding around the text. Up to four values can be entered to set the padding for all four sides, with the first value affecting the top padding, the second value affecting the right padding, and so on, in a clockwise direction. Default Value: null
progression	String	To change the scale type from linear (default) to logarithmic. Accepted Values: ['lin', 'linear', 'log'] Default Value: 'lin'
rectShortcut rect-shortcut	Boolean	Used to force the library to create rectangles using a faster drawing API (instead of painting them like a closed polygon). However, using this would disable effects like rounded borders. It is a performance setting for edge cases. Default Value: false
refLine ref-line	Object	To style the reference line. Default Value: null Chart types: Gauge
refValue ref-value	Number	To set the value the reference line is drawn at. Default Value: 0 Chart types: Gauge
scaleFactor scale-factor	Number	Parameter used to control the range (min/max values) of the scale without forcing fixed values. The parameter will be applied on the pre-calculated min/max values and the result forced on the scale. Default Value: 1
short	Boolean	Automatically shortens large units (e.g. 1000000 -> 1M) Default Value: false Chart types: Gauge
shortUnit short-unit	String	Specifies which unit of measure to use when `short` is set to true. Accepted Values: ['k', 'K', 'm', 'M', 'b', 'B'] Default Value: '' Chart types: Gauge
step	Number	The 'step': attribute sets the value of each step along an axis. When using numeric values along the axis, a numeric value for 'step': will incrementally increase the value of each tick along the axis by the specified step value. When the transform attribute is set to 'type':'date', a number of different step values can then be used to modify the step increments. Accepted Values: [`${number}`, `${number\|''}second`, `${number\|''}minute`, `${number\|''}hour`, `${number\|''}day`, `${number\|''}week`, `${number\|''}month`, `${number\|''}year`] Default Value: 1 Chart types: Gauge
thousandsSeparator thousands-separator	String	Sets the character used to separate thousands. Default Value: ''
tick	Object	Used to style the scale tick marks. Default Value: null
tooltip	Object	Configures the tooltip element, which appears when hovering over an object. Chart types: Gauge
tooltipText tooltip-text	Array.<String>	Sets the tooltip text.
transform	Object	Transforms data to specified format. For example, if data is coded as date and time, `type: 'date'` is specifed in this object, and `scaleX.transform: '%D, %d %M %h:%i %A'` is set, then '1311261385209' will display 'Wed, 19 of May 05:00 PM'. Default Value: null Chart types: Gauge
used	Boolean	Forces the display of the scale, even if its not used on any plot. Default Value: false
values	Array.<Number,String>, Number, String	Sets the scale values. Default Value: []
visible	Boolean	Sets the visibility of the object. Allows you to turn off the object without removing lines of JSON. Default Value: true
zIndex z-index	Number	Sets the z position of the object. Objects with higher z indexes will appear "above" those with lower z index values. Default Value: 1
zoomSnap zoom-snap	Boolean	When zooming is enabled, setting zoom-snap to true snaps the zoom area to the nearest data node as a zoom area is selected. By default, zoom-snap is set to false. Default Value: false
zoomTo zoom-to	Array.<Number>	To specify the node indices the chart will zoom to by default at chart render. This is best used with linear data (or simple array data) with scrollbars or preview charts Default Value: null Chart types: Gauge
zooming	Boolean	To turn on chart zooming on the scale. Default Value: false Chart types: Gauge
