public balloon: AmBalloon

The chart creates AmBalloon class itself. If you want to customize balloon, get balloon instance using this property, and then change balloon's properties. AmBalloon

public borderAlpha: number

Opacity of chart's border. Value range is 0 - 1.

public borderColor: string

Color of chart's border. You should set borderAlpha >0 in order border to be visible. We recommend setting border color directly on a chart's DIV instead of using this property. #000000

public color: string

Text color. #000000

public dataProvider: Array<any>

Array of data objects, for example: [{country:"US", value:524},{country:"UK", value:624},{country:"Lithuania", value:824}]. You can have any number of fields and use any field names. In case of AmMap, data provider should be MapData object.

public fontFamily: string

Font family. Verdana

public fontSize: number

Font size.

default

11

public height: any

Height of a chart. "100%" means the chart's height will be equal to it's container's (DIV) height and will resize if height of the container changes. Set a number instead of percents if your chart's size needs to be fixed.

default

1

public legendDiv: HTMLElement

Reference to the div of the legend.

public numberFormatter: Object

Object with precision, decimalSeparator and thousandsSeparator set which will be used for number formatting. Precision set to -1 means that values won't be rounded. {precision:-1, decimalSeparator:'.', thousandsSeparator:','}

public panEventsEnabled: boolean

This setting affects touch-screen devices only. If a chart is on a page, and panEventsEnabled are set to true, the page won't move if the user touches the chart first. If a chart is big enough and occupies all the screen of your touch device, the user won’t be able to move the page at all. That's why the default value is "false". If you think that selecting/panning the chart or moving/pinching the map is a primary purpose of your users, you should set panEventsEnabled to true.

public percentFormatter: Object

Object with precision, decimalSeparator and thousandsSeparator set which will be used for formatting percent values. {precision:2, decimalSeparator:'.', thousandsSeparator:','}

public prefixesOfBigNumbers: Array<any>

Prefixes which are used to make big numbers shorter: 2M instead of 2000000, etc. Prefixes are used on value axes and in the legend. To enable prefixes, set usePrefixes property to true. [{number:1e+3,prefix:"k"},{number:1e+6,prefix:"M"},{number:1e+9,prefix:"G"},{number:1e+12,prefix:"T"},{number:1e+15,prefix:"P"},{number:1e+18,prefix:"E"},{number:1e+21,prefix:"Z"},{number:1e+24,prefix:"Y"}]

public prefixesOfSmallNumbers: Array<any>

Prefixes which are used to make small numbers shorter: 2μ instead of 0.000002, etc. Prefixes are used on value axes and in the legend. To enable prefixes, set usePrefixes property to true. [{number:1e-24, prefix:"y"},{number:1e-21, prefix:"z"},{number:1e-18, prefix:"a"},{number:1e-15, prefix:"f"},{number:1e-12, prefix:"p"},{number:1e-9, prefix:"n"},{number:1e-6, prefix:"μ"},{number:1e-3, prefix:"m"}]

If true, prefixes will be used for big and small numbers. You can set arrays of prefixes via prefixesOfSmallNumbers and prefixesOfBigNumbers properties.
