Class AmRadarChart

AmRadarChart is the class you have to use for radar and polar chart types.

example

var chart; var chartData = [ {country:"Czech Republic",litres:156.90}, {country:"Ireland",litres:131.10}, {country:"Germany",litres:115.80}, {country:"Australia",litres:109.90}, {country:"Austria",litres:108.30}, {country:"UK",litres:99.00} ];

window.onload = function() { chart = new AmCharts.AmRadarChart(); chart.dataProvider = chartData; chart.categoryField = "country"; chart.startDuration = 2;

var valueAxis = new AmCharts.ValueAxis(); valueAxis.axisAlpha = 0.15; valueAxis.minimum = 0; valueAxis.dashLength = 3; valueAxis.axisTitleOffset = 20; valueAxis.gridCount = 5; chart.addValueAxis(valueAxis);

var graph = new AmCharts.AmGraph(); graph.valueField = "litres"; graph.bullet = "round"; graph.balloonText = "value litres of beer per year" chart.addGraph(graph);

chart.write("chartdiv"); }

constructor(theme: any): AmChart

used when constructing a chart with a theme

Parameters

  • theme: any

Returns

AmChart

Properties

public backgroundColor: string

Background color. You should set backgroundAlpha to >0 value in order background to be visible. We recommend setting background color directly on a chart's DIV instead of using this property. #FFFFFF

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 colors: Array<any>

Specifies the colors of the graphs if the lineColor of a graph is not set. It there are more graphs then colors in this array, the chart picks random color.

default

['#FF6600', '#FCD202', '#B0DE09', '#0D8ECF', '#2A0CD0', '#CD0D74', '#CC0000', '#00CC00', '#0000CC', '#DDDDDD', '#999999', '#333333', '#990000']

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 graphs: Array<any>

The array of graphs belonging to this chart. To add/remove graph use addGraph/removeGraph methods instead of adding/removing graphs directly to array.

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 marginBottom: number

Bottom margin of the chart.

public marginLeft: number

Left margin of the chart.

public marginRight: number

Right margin of the chart.

public marginTop: number

Top margin of the chart.

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 plotAreaBorderAlpha: number

The opacity of plot area's border. Value range is 0 - 1.

public plotAreaBorderColor: string

The color of the plot area's border. Note, the it is invisible by default, as plotAreaBorderAlpha default value is 0. Set it to a value higher than 0 to make it visible.

default

000000

public plotAreaFillAlphas: number

Opacity of plot area. Plural form is used to keep the same property names as our Flex charts'. Flex charts can accept array of numbers to generate gradients. Although you can set array here, only first value of this array will be used.

public plotAreaFillColors: any

You can set both one color if you need a solid color or array of colors to generate gradients, for example: ["#000000", "#0000CC"]

default

FFFFFF

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"}]

public radius: any

Radius of a radar. 0.35

public sequencedAnimation: boolean

Specifies whether the animation should be sequenced or all objects should appear at once.

default

true

public startAlpha: number

default

1

public startDuration: number

Duration of the animation, in seconds.

public startEffect: string

Animation effect. Possible values are ">", "<", elastic" and "bounce".

default

"elastic"

public urlTarget: any

Target of url.

default

this

public usePrefixes: boolean

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

public valueAxes: Array<any>

The array of value axes. To add/remove value axis use addValueAxis/removeValueAxis methods instead of adding/removing axes directly to array. Chart creates one value axis automatically, so if you need only one value axis, you don't need to create it.
