Name	Type	Description

Options

Name	Type	Default	Description
`type`	string	"bar"	Type of chart to create. Possible values are "bar" for barcharts, "pie" for pie charts, "polar-radius" and "polar-area" for polar area charts where values are represented either by the radius or the area of the slices.
`data`	Array.<number>	[1]	Data values the chart has to represent.
`maxValues`	Array.<number> \| "auto"	"auto"	maximal absolute value the data could take. It can be a single numeric value or an array of values with same length as data. In the first case, all values will be represented with the same scale while in the second case, each value will have its own scale. This is useful when one wants to represent multiple variables that are not comparable. If it equals to "auto" (the default) then the maximum absolute value in data is used.
`colors`	Array.<string>	d3.schemeCategory10	Array of colors. If its length is less than the length of data, colors are recycled.
`width`	number	60	Width of the chart when `type` equals 'bar' or maximal diameter of the chart for all other types.
`height`	number	60	Maximal height of barcharts.
`labels`	Array.<string> \| "none" \| "auto"	"none"	Labels to display on the chart. If it equals to "auto" then data values are displayed in a compact way.
`labelMinSize`	number	8	Labels are automatically hidden if the label height is less than this number.
`labelMaxSize`	number	24	Maximal height of labels in pixels.
`labelPadding`	number	2	Padding to apply to labels.
`labelStyle`	string	"font-family:sans-serif"	CSS style to apply to labels
`labelColor`	string	"auto"	Color to apply to labels. If "auto", text will be black or white depending on the background color.
