# plotOptions.dumbbell.lineColor

A separate color for the graph line. By default the line takes the `color` of the series, but the lineColor setting allows setting a separate color for the line without altering the `fillColor`.

In styled mode, the line stroke can be set with the `.highcharts-graph` class name.
