Time Series

The timeseries package is used to hold time series data, often for creating time-based bar or line charts. Each time value can be stored as a float or an integer. Data for multiple series are stored by TimeSeriesSet.

Major structs

  • TimeSeries: a single time series
  • TimeSeriesSet: mulitple time series sets
