Inheritance: AmCoordinateChart → AmChart
AmCoordinateChart is a base class of AmRectangularChart. It can not be instantiated explicitly.
| Property | Type | Default | Description |
|---|---|---|---|
| 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. |
| 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. |
| 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. |
| color | String | #000000 | Text color. |
| colors | Array | ['#FF6600', '#FCD202', '#B0DE09', '#0D8ECF', '#2A0CD0', '#CD0D74', '#CC0000', '#00CC00', '#0000CC', '#DDDDDD', '#999999', '#333333', '#990000'] | 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 | Array | 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 | String | Verdana | Font family. |
| fontSize | Number | 11 | Font size. |
| graphs | Array | 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 | 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. |
| legendDiv | DIV object | Reference to the div of the legend. | |
| 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. |
| plotAreaBorderAlpha | Number | 0 | The opacity of plot area's border. Value range is 0 - 1. |
| plotAreaBorderColor | String | #000000 | 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 | Number | 0 | 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 | String/Array | #FFFFFF | You can set both one color if you need a solid color or array of colors to generate gradients, for example: ["#000000", "#0000CC"] |
| 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. |
| sequencedAnimation | Boolean | true | Specifies whether the animation should be sequenced or all objects should appear at once. |
| startAlpha | Number | 1 | 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 | Number | 0 | Duration of the animation, in seconds. |
| startEffect | String | elastic | Animation effect. Possible values are ">", "<", elastic" and "bounce". |
| urlTarget | String | _self | Target of url. |
| 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. |
| valueAxes | Array | 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 | String | Read-only. Indicates current version of a script. |
| Name | Parameters | Returns | Description |
|---|---|---|---|
| addGraph(graph) | graph - instance of AmGraph | Adds a graph to the chart. | |
| addLabel(x, y, text, align, size, color, rotation, alpha, bold, url) | x - horizontal coordinate y - vertical coordinate text - label's text align - alignment (left/right/center) size - text size color - text color rotation - angle of rotation alpha - label alpha bold - specifies if text is bold (true/false), url - url of a | Adds a label on a chart. You can use it for labeling axes, adding chart title, etc. x and y coordinates can be set in number, percent, or a number with ! in front of it - coordinate will be calculated from right or bottom instead of left or top. | |
| addLegend(legend, legendDivID) | legend - AmLegend, legendDivID - id or reference to legend div (optional) | Adds a legend to the chart. By default, you don't need to create div for your legend, however if you want it to be positioned in some different way, you can create div anywhere you want and pass id or reference to your div as a second parameter. (NOTE: This method will not work on StockPanel.) | |
| addListener(type, handler) | type - string like 'dataUpdated' (should be listed in 'events' section of this class or classes which extend this class). handler - function which is called when event happens | Adds event listener to the object. | |
| addTitle(text, size, color, alpha, bold) | text - text of a title size - font size color - title color alpha - title opacity bold - boolean value indicating if title should be bold. | Adds title to the top of the chart. Pie, Radar positions are updated so that they won't overlap. Plot area of Serial/XY chart is also updated unless autoMargins property is set to false. You can add any number of titles - each of them will be placed in a new line. To remove titles, simply clear titles array: chart.titles = []; and call chart.validateNow() method. | |
| addValueAxis(axis) | axis - instance of ValueAxis | Adds value axis to the chart. One value axis is created automatically, so if you don't want to change anything or add more value axes, you don't need to add it. | |

| showGraphsBalloon(graph) | graph - instance of AmGraph | Show value balloon of a graph. Usually this method is called from the Legend, when you click on the legend text. | |
| unhighlightGraph(graph) | graph - instance of AmGraph | UnhighlightGraph the graph. Usually this method is called from the Legend, when you roll-out the legend entry. | |
| validateData() | This method should be called after data in your data provider changed or a new array was set to dataProvider. After calling this method the chart will parse data and redraw. | ||
| validateNow() | This method should be called after you changed one or more properties of any class. The chart will redraw after this method is called. | ||
