AmRadarChart – amCharts Version 2 Documentation

Type class

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");
}

Inheritance

AmRadarChart extends AmCoordinateChart.

AmRadarChart is not extended by any other symbol.

Properties

marginBottom #	Type `number` Default `0` Bottom margin of the chart.
marginLeft #	Type `number` Default `0` Left margin of the chart.
marginRight #	Type `number` Default `0` Right margin of the chart.
marginTop #	Type `number` Default `0` Top margin of the chart.
radius #	Type `Number/String` Default `35%` Radius of a radar.
colors #	Type `array` Default `['#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.
graphs #	Type `array` Default 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.
plotAreaBorderAlpha #	Type `number` Default `0` Inherited from `AmCoordinateChart` The opacity of plot area's border. Value range is 0 - 1.
plotAreaBorderColor #	Type `string` Default `#000000` Inherited 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 `number` Default `0` Inherited 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/Array` Default `#FFFFFF` Inherited 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"]
sequencedAnimation #	Type `boolean` Default `true` Inherited from `AmCoordinateChart` Specifies whether the animation should be sequenced or all objects should appear at once.
startAlpha #	Type `number` Default `1` Inherited 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 `number` Default `0` Inherited from `AmCoordinateChart` Duration of the animation, in seconds.
startEffect #	Type `string` Default `elastic` Inherited from `AmCoordinateChart` Animation effect. Possible values are ">", "<", elastic" and "bounce".
urlTarget #	Type `string` Default `_self` Inherited from `AmCoordinateChart` Target of url.
valueAxes #	Type `array` Default 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.
backgroundColor #	Type `string` Default `#FFFFFF` Inherited 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 `AmBalloon` Default `AmBalloon` Inherited 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 `number` Default `0` Inherited from `AmChart` Opacity of chart's border. Value range is 0 - 1.
borderColor #	Type `string` Default `#000000` Inherited 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 `string` Default `#000000` Inherited from `AmChart` Text color.
dataProvider #	Type `array` Inherited 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 `string` Default `Verdana` Inherited from `AmChart` Font family.
fontSize #	Type `number` Default `11` Inherited from `AmChart` Font size.
height #	Type `Number/String` Default `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 object` Inherited from `AmChart` Reference to the div of the legend.
numberFormatter #	Type `object` Default `{ 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 `boolean` Default `false` Inherited 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 `string` Inherited from `AmChart` Specifies path to the folder where images like resize grips, lens and similar are.
percentFormatter #	Type `object` Default `{ precision:2, decimalSeparator:'.', thousandsSeparator:', ' }` Inherited from `AmChart` Object with precision, decimalSeparator and thousandsSeparator set which will be used for formatting percent values.
prefixesOfBigNumbers #	Type `array` Default `[{ 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 `array` Default `[{ 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.
usePrefixes #	Type `boolean` Default `false` Inherited from `AmChart` If true, prefixes will be used for big and small numbers. You can set arrays of prefixes via prefixesOfSmallNumbers and prefixesOfBigNumbers properties.
version #	Type `string` Inherited from `AmChart` Read-only. Indicates current version of a script.
