| 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. |
| accessibleDescription | String | Description which will be added to | |
| accessibleLabel | String | [[title]]: [[percents]]% [[value]] [[description]] | Text which screen readers will read if user rolls-over the slice or sets focus using tab key (this is possible only if tabIndex property of AmSlicedChart is set to some number). Text is added as aria-label tag. Note - not all screen readers and browsers support this. |
| accessibleTitle | String | Description which is added to | |
| addClassNames | Boolean | false | Specifies, if class names should be added to chart elements. |
| adjustPrecision | Boolean | false | Sometimes, because of a rounding, percent of a sum of all slices is not equal to 100%. If you set this to true, when this case happens, number of decimals will be increased so that sum would become 100%. |
| 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"} |
| alpha | Number | 1 | Opacity of all slices. |
| alphaField | String | Name of the field in chart's dataProvider which holds slice's alpha. | |
| angle | Number | 0 | Pie lean angle (for 3D effect). Valid range is 0 - 90. |
| 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. |
| 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. |
| balloonFunction | If you set some function, the graph will call it and pass GraphDataItem object to it. This function should return a string which will be displayed in a balloon. | ||
| balloonText | String | [[title]]: [[percents]]% ([[value]])\n[[description]] | Balloon text. The following tags can be used: [[value]], [[title]], [[percents]], [[description]] or any other field name from your data provider. HTML tags can also be used. |
| baseColor | Color | Color of the first slice. All the other will be colored with darker or brighter colors. Use brightnessStep to set intensity of color change for each subsequent slice. | |
| 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. |
| brightnessStep | Number | 20 | If you set baseColor to some color, the chart will not use colors array to color each slice but rather this setting to color the first slice with gradually increasing (or decreasing) brightness for each subsequent slice. This setting describes the intensity of each step. Set to positive number to make the color brighter with each slice. Set to negative to make the colors darker for subsequent slices. |
| chartData | Array[Object] | Read-only. Array of Slice objects. | |
| classNameField | String | If this field is set and addClassNames is enabled, the slice element will have this class name set. | |

You can have any number of fields and use any field names. In case of AmMap, data provider should be MapData object. The data set data. Important: if you are using date/time-based category axis, the data points needs to come pre-ordered in ascending order. Data with incorrect order might result in visual and functional glitches on the chart. | |
| decimalSeparator | String | . | Decimal separator. |

| 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. |
| hideLabelsPercent | Number | 0 | Slices with percent less then hideLabelsPercent won't display labels This is useful to avoid cluttering up the chart, if you have a lot of small slices. 0 means all labels will be shown. |

| labelTickAlpha | Number | 0.2 | Label tick opacity. Value range is 0 - 1. |
| labelTickColor | Color | #000000 | Label tick color. |
| 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. | |
| listeners | Array[Object] | You can add listeners of events using this property. Example: listeners = [{"event":"dataUpdated", "method":handleEvent}]; | |

| 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 | amcharts/ | Specifies absolute or relative path to amCharts files, i.e. "amcharts/". (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 chart config, the chart will assume the path from the global variable. This allows setting amCharts path globally. I.e.: var AmCharts_path = "/libs/amcharts/"; "path" parameter will be used by the charts 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. | |
| patternField | String | Field name in your data provider which holds pattern information. Value of pattern should be object with url, width, height of an image, optionally it might have x, y, randomX and randomY values. For example: {"url":"../amcharts/patterns/black/pattern1.png", "width":4, "height":4}. Check amcharts/patterns folder for some patterns. You can create your own patterns and use them. Note, x, y, randomX and randomY properties won't work with IE8 and older. 3D bar/Pie charts won't work properly with patterns. | |
| percentPrecision | Number | 2 | Precision of percent values. -1 means percent values won't be rounded at all and show as they are. |
| pieX | Number/String | You can set fixed position of a pie center, in pixels or in percents. | |
| pieY | Number/String | You can set fixed position of a pie center, in pixels or in percents. | |
| precision | Number | -1 | Precision of values. -1 means values won't be rounded at all and show as they are. |

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. |
| 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. |
| pulledField | String | Name of the field in chart's dataProvider which holds a boolean value telling the chart whether this slice must be pulled or not. | |
| pullOutDuration | Number | 1 | Pull out duration, in seconds. |

| pullOutRadius | Number/String | 20% | Pull out radius, in pixels or percents |
| radius | Number/String | Radius of a pie, in pixels or percents. By default, radius is calculated automatically. | |
| responsive | Object | A config object for Responsive plugin. Please refer to the following page for more information. | |
| sequencedAnimation | Boolean | true | Specifies whether the animation should be sequenced or all slices should appear at once. |
| showZeroSlices | Boolean | false | If you set this to true, the chart will display outlines (if visible) and labels for slices even if their value is 0. |
| startAlpha | Number | 0 | Initial opacity of all slices. Slices will fade in from startAlpha. |
| startAngle | Number | 90 | Angle of the first slice, in degrees. This will work properly only if "depth3D" is set to 0. If "depth3D" is greater than 0, then there can be two angles only: 90 and 270. Value range is 0-360. |
| startDuration | Number | 1 | Duration of the animation, in seconds. |
| startEffect | String | bounce | Animation effect. Possible values are: easeOutSine, easeInSine, elastic, bounce |
| startRadius | Number/String | 500% | Radius of the positions from which the slices will fly in. |
| 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. |
| tabIndex | Number | In case you set it to some number, the chart will set focus on a slice (starting from first) when user clicks tab key. When a focus is set, screen readers like NVDA Screen reader will read label which is set using accessibleLabel property of AmSlicedChart. Note, not all browsers and readers support this. | |
| 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. |

| 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, gantt, stock. | |
| urlField | String | Name of the field in chart's dataProvider which holds url which would be accessed if the user clicks on a slice. | |
| urlTarget | String | _self | If url is specified for a slice, it will be opened when user clicks on it. urlTarget specifies target of this url. Use _blank if you want url to be opened in a new window. |
| 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. |
| valueField | String | Name of the field in chart's dataProvider which holds slice's value. | |
| version | String | Read-only. Indicates current version of a script. | |
| visibleInLegendField | String | Use this field to selectively specify which slice is shown in legend. It should be set to a boolean field in data (that holds either true or false). For example if you set visibleInLegendField to "showInLegend", all slices that have showInLegend: false in their data will not be shown in the legend. |
