Class: Point

Members

category :number|string

For categorized axes this property holds the category name for the point. For other axes it holds the X value.

Type:

• number | string

color :Highcharts.ColorString|Highcharts.GradientColorObject|Highcharts.PatternObject|undefined

The point's current color.

Type:

• Highcharts.ColorString | Highcharts.GradientColorObject | Highcharts.PatternObject | undefined

colorIndex :number|undefined

The point's current color index, used in styled mode instead of color. The color index is inserted in class names used for styling.

Type:

• number | undefined

dataGroup :Highcharts.DataGroupingInfoObject|undefined

Highcharts Stock only. If a point object is created by data grouping, it doesn't reflect actual points in the raw data. In this case, the dataGroup property holds information that points back to the raw data.

• dataGroup.start is the index of the first raw data point in the group.

• dataGroup.length is the amount of points in the group.

Type:

• Highcharts.DataGroupingInfoObject | undefined

Try it

• Click to inspect raw data points.

graphic :Highcharts.SVGElement|undefined

SVG graphic representing the point in the chart. In some cases it may be a hidden graphic to improve accessibility.

Typically this is a simple shape, like a rect for column charts or path for line markers, but for some complex series types like boxplot or 3D charts, the graphic may be a g element containing other shapes. The graphic is generated the first time Highcharts.Series#drawPoints runs, and updated and moved on subsequent runs.

Type:

• Highcharts.SVGElement | undefined

See also:

• Highcharts.Point#graphics

graphics :Array.<Highcharts.SVGElement>|undefined

Array for multiple SVG graphics representing the point in the chart. Only used in cases where the point can not be represented by a single graphic.

Type:

• Array.<Highcharts.SVGElement> | undefined

See also:

• Highcharts.Point#graphic

<readonly> index :number

Contains the point's index in the Series.points array.

Type:

• number

name :string

The name of the point. The name can be given as the first position of the point configuration array, or as a name property in the configuration:

Type:

• string

Example

// Array config
data: [
    ['John', 1],
    ['Jane', 2]
]

// Object config
data: [{
       name: 'John',
       y: 1
}, {
    name: 'Jane',
    y: 2
}]

options :Highcharts.PointOptionsObject

The point's options as applied in the initial configuration, or extended through Point.update.

In TypeScript you have to extend PointOptionsObject via an additional interface to allow custom data options:

declare interface PointOptionsObject {
    customProperty: string;
}

• Highcharts.PointOptionsObject

percentage :number|undefined

The percentage for points in a stacked series or pies.

Returns:

string .

The class names.

getLabelConfig()

Return the configuration hash needed for the data label and tooltip formatters.

Returns:

Highcharts.PointLabelObject .

Abstract object used in formatters and formats.

getZone()

In a series with zones, return the zone that the point belongs to.

Returns:

Highcharts.SeriesZonesOptionsObject .

The zone item.

haloPath(size)

Get the path definition for the halo, which is usually a shadow-like circle around the currently hovered point.

Parameters:

size	number	The radius of the circular halo.

Returns:

Highcharts.SVGPathArray .

The path definition.

init(series, options [, x])

Initialize the point. Called internally based on the series.data option.

Parameters:

Name	Type	Argument	Description
series	Highcharts.Series		The series object containing this point.
options	Highcharts.PointOptionsType		The data in either number, array or object format.
x	number	<optional>	Optionally, the X value of the point.

Parameters:

Name	Type	Argument	Description
e	Highcharts.PointerEventObject	<optional>	The event arguments.

optionsToObject(options)

Transform number or array configs into objects. Also called for object configs. Used internally to unify the different configuration formats for points. For example, a simple number 10 in a line series will be transformed to { y: 10 }, and an array config like [1, 10] in a scatter series will be transformed to { x: 1, y: 10 }.

remove( [redraw] [, animation])

Remove a point and optionally redraw the series and if necessary the axes

Parameters:

Name	Type	Argument	Default	Description
redraw	boolean	<optional>	true	Whether to redraw the chart or wait for an explicit call. When doing more operations on the chart, for example running point.remove() in a loop, it is best practice to set redraw to false and call chart.redraw() after.

Try it

• Remove point and confirm.
• Remove pie slice.
