You are browsing a class reference for deprecated Version 2 of the JavaScript Charts.
Documentation for other versions: amCharts 4 (current) or amCharts 3.
Inheritance: AmMap → AmChart
AmMap is the main class of the AmMap application. Example:
var map = new AmCharts.AmMap();
map.pathToImages = "http://www.ammap.com/lib/images/";
map.dataProvider = {mapVar: AmCharts.maps.worldLow};
map.write("mapdiv");
| Property | Type | Default | Description |
|---|---|---|---|
| allowClickOnSelectedObject | Boolean | true | Specifies if user can repeatedly click on already selected object. |
| allowMultipleDescriptionWindows | Boolean | false | Specifies if multiple description windows at a time are allowed. When set to false, previously opened window is closed when opening a new one. |
| areasSettings | AreasSettings | AreasSettings | Common settings of areas. |
| backgroundColor | String | #FFFFFF | 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. |
| backgroundZoomsToTop | Boolean | false | Specifies if clicking on the "water" zooms to the "top" |
| balloon | AmBalloon | 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. |
| balloonLabelFunction | Function | Method which will be called by the map when a balloon with some text is displayed. You can use it to change the default text of a balloon.When this function is called, mapObject and map references are passed to it: balloonLabelFunction(mapObject, ammap); You can extract any data from mapObject and return new balloon text. | |
| borderAlpha | Number | 0 | Opacity of chart's border. Value range is 0 - 1. |
| borderColor | String | #000000 | 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. |
| centerMap | Boolean | true | Specifies if the map should be centered. |
| color | String | #000000 | Text color. |
| colorSteps | Number | 5 | If you set values for MapAreas, they are filled with colors between color and colorSolid (both set in AreasSettings). colorSteps property specifies how many different colors should be used. Set this to some big number like 100 if you want each area to be filled with a different shade of color (according to it's value). |
| dataProvider | MapData | Data provider of the map. | |
| developerMode | Boolean | false | When developer mode is set to true, you can click anywhere on the map while SHIFT key is pressed to trigger a writeDevInfo event. All the information about current map position/zoom will be transferred to the event handler. |
| dragMap | Boolean | true | Specifies if the map is draggable. |
| fitMapToContainer | Boolean | true | Specifies if the map should be resized to fit to the stage. |
| fontFamily | String | Verdana | Font family. |
| fontSize | Number | 11 | Font size. |
| height | Number/String | 100% | 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. |
| imagesSettings | ImagesSettings | ImagesSettings | Common settings of images. |
| legendDiv | DIV object | Reference to the div of the legend. | |
| linesAboveImages | Boolean | true | You can specify whether lines should be above or below images. |
| linesSettings | LinesSettings | LinesSettings | Common settings of lines. |
| mapVar | Variable | ||
| maxValue | Number | Use this property in case you set values for your areas and wish to set a different maxValue. These values are used when choosing a color for an area. | |
| minValue | Number | Use this property in case you set values for your areas and wish to set a different minValue (it's 0 by default). These values are used when choosing a color for an area. | |
| mouseWheelZoomEnabled | Boolean | false | Specifies if zooming with mouse wheel is enabled. |
| numberFormatter | Object | {precision:-1, decimalSeparator:'.', thousandsSeparator:','} | 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 | Boolean | false | 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 | String | Specifies path to the folder where images like resize grips, lens and similar are. | |
| percentFormatter | Object | {precision:2, decimalSeparator:'.', thousandsSeparator:','} | Object with precision, decimalSeparator and thousandsSeparator set which will be used for formatting percent values. |
| prefixesOfBigNumbers | Array | [{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"}] | 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 | Array | [{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"}] | 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. |
