Inheritance: AmMap → AmChart

Base class of AmCharts. It can not be instantiated explicitly. It's makeChart method gives you the possibility to create maps easily with a single object.

### Example

    var map = AmCharts.makeChart("mapdiv",{
      "type": "map",
      "dataProvider": {
        "map": "worldHigh",
        ...
      }
    });

### Properties Hide inherited Show inherited

Property | Type | Default | Description
--- | --- | --- | ---
accessible | Boolean | true | When enabled, chart adds aria-label attributes to columns, bullets or map objects. You can control values of these labels using properties like accessibleLabel of AmGraph. Note, not all screen readers support these tags. We tested this mostly with NVDA Screen reader. WAI-ARIA is now official W3 standard, so in future more readers will handle this well. We will be improving accessibility on our charts, so we would be glad to hear your feedback.
accessibleTitle | String |  | <title> element will be added to <svg> node if you set any. It is read by most of the screen readers.
addClassNames | Boolean | false | Specifies, if class names should be added to chart elements.
allLabels | Array[Label] | [] | Array of Labels. Example of label object, with all possible properties: {"x": 20, "y": 20, "text": "this is label", "align": "left", "size": 12, "color": "#CC0000", "alpha": 1, "rotation": 0, "bold": true, "url": "http://www.amcharts.com"}
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.
areasClasses | Object |  | You can create multiple AreasSettings objects and then set them using this property. For example, map.areasClasses["rivers"] = riversSettings; The class "rivers" should be set for your svg areas which should use the riversSettings object.
areasSettings | AreasSettings | AreasSettings | Common settings of areas.
autoDisplay | Boolean | false | If you set it to true the chart will automatically monitor changes of display style of chart’s container (or any of it’s parents) and will render chart correctly if it is changed from none to block. We recommend setting it to true if you change this style at a run time, as it affects performance a bit.
autoResize | Boolean | true | Set this to false if you don't want chart to resize itself whenever its parent container size changes.
autoTransform | Boolean | false | If you set it to true and your chart div (or any of the parent div) has css scale applied, the chart will position mouse at a correct position. Default value is false because this operation consumes some CPU and quite a few people are using css transfroms.
backgroundAlpha | Number | 0 | Opacity of background. Set it to >0 value if you want backgroundColor to work. However we recommend changing div's background-color style for changing background color.
backgroundColor | Color | #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 | Color | #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.
classNamePrefix | String | amcharts | This prefix is added to all class names which are added to all visual elements of a chart in case addClassNames is set to true.
color | Color | #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).
creditsPosition | String | top-left | Non-commercial version only. Specifies position of link to amCharts site. Allowed values are: top-left, top-right, bottom-left and bottom-right.
dataLoader | Object |  | A config object for Data Loader plugin. Please refer to the following page for more information.
dataProvider | MapData |  | Data provider of the map.
decimalSeparator | String | . | Decimal separator.
defs | Object |  | Using this property you can add any additional information to SVG, like SVG filters or clip paths. The structure of this object should be identical to XML structure of a object you are adding, only in JSON format.
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.
export | Object |  | Export config. Specifies how export to image/data export/print/annotate menu will look and behave. You can find a lot of examples in amcharts/plugins/export folder. More details can be found here.
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.
forceNormalize | Boolean | false | If you set it to true, the map will redraw all the areas, normalizing paths. This might be needed if you use SVG filters with areas. Might not work with maps containing complex paths (with arcs and similar).
handDrawn | Boolean | false | If you set this to true, the lines of the chart will be distorted and will produce hand-drawn effect. Try to adjust chart.handDrawScatter and chart.handDrawThickness properties for a more scattered result.
handDrawScatter | Number | 2 | Defines by how many pixels hand-drawn line (when handDrawn is set to true) will fluctuate.
handDrawThickness | Number | 1 | Defines by how many pixels line thickness will fluctuate (when handDrawn is set to true).
hideBalloonTime | Number | 150 | Time, in milliseconds after which balloon is hidden if the user rolls-out of the object. Might be useful for AmMap to avoid balloon flickering while moving mouse over the areas. Note, this is not duration of fade-out. Duration of fade-out is set in AmBalloon class.
imagesSettings | ImagesSettings | ImagesSettings | Common settings of images.
language | String |  | Allows changing language easily. Note, you should include language js file from amcharts/lang or ammap/lang folder and then use variable name used in this file, like chart.language = "de"; Note, for maps this works differently - you use language only for country names, as there are no other strings in the maps application.
legend | AmLegend |  | Legend of a chart.
legendDiv | String |  | Read-only. 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.
listeners | Array[Object] |  | You can add listeners of events using this property. Example: listeners = [{"event":"dataUpdated", "method":handleEvent}];
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 | 0 | 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.
panEventsEnabled | Boolean | true | 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. 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, otherwise - false.
path | String | ammap/ | Specifies absolute or relative path to amCharts files, i.e. "ammap/". (where all .js files are located) If relative URLs are used, they will be relative to the current web page, displaying the chart. You can also set path globally, using global JavaScript variable AmCharts_path. If this variable is set, and "path" is not set in map config, the mapwill assume the path from the global variable. This allows setting amCharts path globally. I.e.:
    var AmCharts_path = "/libs/ammap/";
"path" parameter will be used by the maps to locate it's files, like images, plugins or patterns.
pathToImages | String |  | Specifies path to the folder where images like resize grips, lens and similar are. IMPORTANT: Since V3.14.12, you should use "path" to point to amCharts directory instead. The "pathToImages" will be automatically set and does not need to be in the chart config, unless you keep your images separately from other amCharts files.
percentPrecision | Number | 2 | Precision of percent values. -1 means percent values won't be rounded at all and show as they are.
precision | Number | -1 | Precision of values. -1 means values won't be rounded at all and show as they are.
prefixesOfBigNumbers | Array[Object] | [{"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[Object] | [{"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.
preventDragOut | Boolean | false | If set to true, user won't be able to drag map out of the visible area.
processCount | Number | 1000 | If processTimeout is > 0, 1000 data items will be parsed at a time, then the chart will make pause and continue parsing data until it finishes.
processTimeout | Number | 0 | If you set it to 1 millisecond or some bigger value, chart will be built in chunks instead of all at once. This is useful if you work with a lot of data and the initial build of the chart takes a lot of time, which freezes the whole web application by not allowing other processes to do their job while the chart is busy.
projection | String | mercator | Projection of the map. Projection can be also set in SVG map - all svg maps which are distributed with amMap have projection set in SVG. Available values are: "winkel3", "eckert3", "eckert5", "eckert6", "miller", "equirectangular" and "mercator" (default).
responsive | Object |  | A config object for Responsive plugin. Please refer to the following page for more information.

showAreasInList | Boolean | true | Specifies if MapAreas should be displayed in the ObjectList.
showBalloonOnSelectedObject | Boolean | true | Specifies if balloon should be displayed when hovering currently seleced object.
showDescriptionOnHover | Boolean | false | Specifies if description window should be shown when user hovers over the object.

showLinesInList | Boolean | false | Specifies if MapLines should be displayed in the ObjectList.
showObjectsAfterZoom | Boolean | false | Specifies if child objects should be added to stage only after the map zoomed to the final position.
smallMap | SmallMap |  | Small map displays a small map indicating zoom level and position.
svgIcons | Boolean | true | Charts will use SVG icons (some are loaded from images folder and some are drawn inline) if browser supports SVG. his makes icons look good on retina displays on all resolutions.
tapToActivate | Boolean | true | Charts which require gestures like swipe (charts with scrollbar/cursor) or pinch (maps) used to prevent regular page scrolling and could result page to stick to the same spot if the chart occupied whole screen. Now, in order these gestures to start working user has to touch the chart/maps once. Regular touch events like touching on the bar/slice/map area do not require the first tap and will show balloons and perform other tasks as usual. If you have a map or chart which occupies full screen and your page does not require scrolling, set tapToActivate to false – this will bring old behavior back.
theme | String | none | Theme of a chart. Config files of themes can be found in amcharts/themes/ folder. More info about using themes.
thousandsSeparator | String | , | Thousands separator.
titles | Array[Title] | [] | Array of Title objects.
touchClickDuration | Number | 0 | If you set it to 200 (milliseconds) or so, the chart will fire clickGraphItem or clickSlice (AmSlicedChart) or clickMapObject only if user holds his/her finger for 0.2 seconds (200 ms) on the column/bullet/slice/map object.
type | String |  | Type of a chart. Required when creating chart using JSON. Possible types are: serial, pie, xy, radar, funnel, gauge, map, stock.
useHandCursorOnClickableOjects | Boolean | true | pecifies if hand cursor should be displayed when mouse moves over a clickable object.
useObjectColorForBalloon | Boolean | true | Specifies if balloon should use color of currenlty hovered object.
usePrefixes | Boolean | false | If true, prefixes will be used for big and small numbers. You can set arrays of prefixes via prefixesOfSmallNumbers and prefixesOfBigNumbers properties.
valueLegend | ValueLegend |  | Value legend displays a color range used by areas (in case you set values for your areas).
version | String |  | Read-only. Indicates current version of a script.
zoomControl | ZoomControl | ZoomControl | Zoom control of the map.
zoomDuration | Number | 1 | Duration of zoom animation, in seconds.
zoomOnDoubleClick | Boolean | true | Specifies if the map should be zoomed-in when user double clicks anywhere on the map (except objects which are clickable).
