AmRadarChart

Type class

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

Example:

var chart;

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

window.onload = function() {
  chart = new AmCharts.AmRadarChart();
  chart.dataProvider = chartData;
  chart.categoryField = &quot;country&quot;;
  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 = &quot;litres&quot;;
  graph.bullet = &quot;round&quot;;
  graph.balloonText = &quot;`value` litres of beer per year&quot;
  chart.addGraph(graph);
  
  chart.write(&quot;chartdiv&quot;);
}```

30 inherited items

backgroundColor

Type stringDefault #FFFFFFInherited from AmChart

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.

balloon

Type AmBalloonDefault AmBalloonInherited from AmChart

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

borderAlpha

Type numberDefault 0Inherited from AmChart

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

borderColor

Type stringDefault #000000Inherited from AmChart

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.

color

Type stringDefault #000000Inherited from AmChart

Text color.

colors

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

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.

dataProvider

Type arrayInherited from AmChart

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.

fontFamily

Type stringDefault VerdanaInherited from AmChart

Font family.

fontSize

Type numberDefault 11Inherited from AmChart

Font size.

graphs

Type arrayDefault Inherited from AmCoordinateChart

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

height

Type Number/StringDefault 100%Inherited from AmChart

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.

legendDiv

Type DIV objectInherited from AmChart

Reference to the div of the legend.

numberFormatter

Type objectDefault {precision:-1, decimalSeparator:'.', thousandsSeparator:','}Inherited from AmChart

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.

panEventsEnabled

Type booleanDefault falseInherited from AmChart

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.

pathToImages

Type stringInherited from AmChart

Specifies path to the folder where images like resize grips, lens and similar are.

percentFormatter

Type objectDefault {precision:2, decimalSeparator:'.', thousandsSeparator:','}Inherited from AmChart

Object with precision, decimalSeparator and thousandsSeparator set which will be used for formatting percent values.

Type numberDefault 0Inherited from AmCoordinateChart

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

plotAreaBorderColor

Type stringDefault #000000Inherited from AmCoordinateChart

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.

plotAreaFillAlphas

Type numberDefault 0Inherited from AmCoordinateChart

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.

plotAreaFillColors

Type String/ArrayDefault #FFFFFFInherited from AmCoordinateChart

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

prefixesOfBigNumbers

Type arrayDefault [{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"}]Inherited from AmChart

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.

prefixesOfSmallNumbers

Type arrayDefault [{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"}]Inherited from AmChart

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.

sequencedAnimation

Type booleanDefault trueInherited from AmCoordinateChart

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

startAlpha

Type numberDefault 1Inherited from AmCoordinateChart

The initial opacity of the column/line. If you set startDuration to a value higher than 0, the columns/lines will fade in from startAlpha. Value range is 0 - 1.

startDuration

Type numberDefault 0Inherited from AmCoordinateChart

Duration of the animation, in seconds.

startEffect

Type stringDefault elasticInherited from AmCoordinateChart

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

urlTarget

Type stringDefault _selfInherited from AmCoordinateChart

Target of url.

usePrefixes

Type booleanDefault falseInherited from AmChart

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

valueAxes

Type arrayDefault Inherited from AmCoordinateChart

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.

version

Type stringInherited from AmChart

Read-only. Indicates current version of a script.

Methods

25 inherited items
