Line Series

Line series visualize data as a collection of points connected by a line. This line can be broken, smooth, or step-like, which corresponds to the Line, Spline, and Step Line series types.

Line series also include stacked series types: Stacked Line and Stacked Spline. In such series, the value of each next point is counted off from the previous point with the same argument. As a result, series are put in a stack. Very similar to stacked series are full-stacked series - Full-Stacked Line and Full-Stacked Spline. In these series, the sum of all point values by a given argument is considered 100%, and each individual point value is recalculated to be a share of these 100%.

To specify one or another series type, assign its name to the series[].type property. You can configure:

  • Each series individually using the series array;
  • All series in the Chart using the commonSeriesSettings object;
  • All series of a specific type using objects nested in commonSeriesSettings: line, spline, stepline, etc.
