Arguments

`.Object`	AmChart.
`allLabels`	`list` of Label. Example of a label object, with all possible properties: label(x = 20, y = 20, text = "this is a label", align = "left", size = 12, color = "#CC0000", alpha = 1, rotation = 0, bold = TRUE, url = "http=//www.amcharts.com"). Run `api("Label")` for more informations.
`arrows`	`list` of GaugeArrow. Only valid for gauge charts. Run `api("GaugeArrow")` for more informations.
`axes`	`list` of GaugeAxis properties. Only valid for gauge charts. Run `api("GaugeAxis")` for more informations.
`balloon`	AmBalloon. Creates the balloons (tooltips) of the chart. It follows the mouse cursor when you roll-over the data items. The framework automatically generates the instances you just have to adjust the appearance to your needs. Run `api("AmBalloon")` for more informations.
`categoryAxis`	CategoryAxis. Read-only. Chart creates category axis itself. If you want to change some properties, you should get this axis from the chart and set properties to this object. Run `api("CategoryAxis")` for more informations.
`categoryField`	`character`, category field name indicates the name of the field in your dataProvider object which will be used for category axis values.
`chartCursor`	ChartCursor. Chart's cursor. Run `api("ChartCursor")` for more informations.
`chartScrollbar`	ChartScrollbar. Chart's scrollbar. Run `api("ChartScrollbar")` for more informations.
`creditsPosition`	`character`, specifies position of the amCharts' website link. Allowed values are: "top-left", "top-right", "bottom-left" and "bottom-right".
`dataProvider`	`data.frame`, containing the data.
`graphs`	`list` of AmGraph. Creates the visualization of the data in following types: line, column, step line, smoothed line, olhc and candlestick. Run `api("AmGraph")` for more informations.
`graph`	AmGraph. Only valid for Gantt charts. Gant chart actually creates multiple graphs (separate for each segment). Properties of this graph are passed to each of the created graphs - this allows you to control the look of segments. Run `api("AmGraph")` for more informations.
`guides`	`list` of Guide. Instead of adding guides to the axes, you can push all of them to this array. In case guide has category or date defined, it will automatically be assigned to the category axis, otherwise to the first value axis, unless you specify a different valueAxes for the guide. Run `api("Guide")` for more informations.
`legend`	AmLegend. Legend of a chart. Run `api("AmLegend")` for more informations.
`segmentsField`	`character`, segments field in your data provider. Only valid for Gantt Charts.
`theme`	`character`, theme of a chart. Config files of themes can be found in amcharts/themes/ folder. See https://www.amcharts.com/docs/v3/tutorials/working-with-themes/.
`titles`	`list` of Title. Run `api("Title")` for more informations.
`trendLines`	`list` of TrendLine objects added to the chart. You can add trend lines to a chart using this list or access already existing trend lines. Run `api("TrendLine")` for more informations.
`type`	`character`, possible types are: "serial", "pie", "radar", "xy", "radar", "funnel", "gauge", "stock". See details about using argument type. (type map is in development).
`valueAxes`	`list` of ValueAxis. Chart creates one value axis automatically, so if you need only one value axis, you don't need to create it. Run `api("ValueAxis")` for more informations.
`valueAxis`	ValueAxis. Only valid for Gantt Charts. Set it's type to "date" if your data is date or time based. Run `api("ValueAxis")` for more informations.
`valueScrollbar`	ChartScrollbar. Value scrollbar, enables scrolling value axes.
`...`	In case of constructor `new("AmChart")` or `amChart()` Dots represent other properties to set to the AmChart object. See https://docs.amcharts.com/3/javascriptstockchart/AmChart. In case of setters, dots represent properties of the object to add. See examples.
`marginLeft`	`character`, left margin of the chart.
`marginRight`	`character`, right margin of the chart.
`label`	(optional) Label. Argument of method `addLabel`.
`arrow`	(optional) GaugeArrow. Argument of method `addArrow`.
`axe`	(optional) GaugeAxis. Argument of deprecated method `addAxe`.
`axis`	(optional) GaugeAxis. same as axe.
`amBalloon`	AmBalloon, argument of method 'setBalloon'.
`url`	`character`.
`format`	`character`.
`keepNA`	object of class `logical`, default `TRUE`. Indicates if `NULL` values have to be kept or ignored.
`amGraph`	(optional) AmGraph.
`guide`	(optional) Guide. Argument of method `addGuide`.
`amLegend`	(optional) AmLegend.
`categoryIDs`	`numeric`, see details.
`sgts`	`data.frame` ( or `list` of `data.frame` for multiple add ).
`data`	`data.frame`. Data to draw at the second level, after clicking on the column.
`.subObject`	AmChart.
`title`	(optional) Title, argument of method `addTitle`.
`trendLine`	(optional) TrendLine. Argument of method `addTrendLine`.

Details

amAngularGaugeChart is a shortcut for instantiating AmChart of type gauge.

amFunnelChart is a shortcut for instantiating AmChart of type funnel.

amRadarChart is a shortcut for instantiating AmChart of type radar.

amSerialChart is a shortcut constructor for instantiating AmChart of type serial.

amPieChart is a shortcut constructor for instantiating AmChart of type pie.

amGanttChart is a constructor for instantiating AmChart of type gantt.

amXYChart is a shortcut constructor for instantiating AmChart of type xy.

Method 'addAxe' is deprecated, use 'addAxis'.

Method setGraph is only valid for Gantt Charts.

'addSubData' allows to add subdata for a chart with drilldown. In this case, categoryIDs indicates corresponding indice(s) of the dataProvider where to add the data.

For method addValueAxis: valueAxis is optional. Method addValueAxes is deprecated.

Method setValueAxis is only valid for Gantt charts.

Value

(updated) AmChart with given properties.
