data property

List<List>? data
getter/setter pair

An array of data points for the series. For the streamgraph series type, points can be given in the following ways:

  1. An array of numerical values. In this case, the numerical values will be interpreted as y options. The x values will be automatically calculated, either starting at 0 and incremented by 1, or from pointStart and pointInterval given in the series options. If the axis has categories, these will be used. Example:

  2. An array of arrays with 2 values. In this case, the values correspond to x,y. If the first value is a string, it is applied as the name of the point, and the x value is inferred.

  3. An array of objects with named values. The following snippet shows only a few settings, see the complete options set below. If the total number of data points exceeds the series' turboThreshold, this option is not available.
