Map line series#

A mapline series is a special case of the map series where the value colors are applied to the strokes rather than the fills. It can also be used for freeform drawing of lines in the map.

Configuration#

To create a mapline series, set the series type to mapline. More information about data formatting and available options can be found in the API. As you can see in the demo above we can create a mapline series in combination with a standard map series, then plot our shape data via the geometry options. To achieve a better separation between the structure and the data, it is recommended to use mapData to define the geometry instead of defining it on the data points themselves.

The geometry object is compatible to that of a feature in GeoJSON, so features of GeoJSON can be passed directly into the data, optionally after first filtering and processing it.
