    • update

      public void update(float newData)
      Pushes a new data point.

      Exponential moving average is calculated, and the history is updated. This method needs to be called periodically and regularly, and it represents the raw data stream.

    • getHistory

      @Exported public float[] getHistory()
      Gets the history data of the exponential moving average. The returned array should be treated as read-only and immutable.
      Always non-null, contains at least one entry.
    • getLatest

      @Exported public float getLatest()
      Gets the most up-to-date data point value. getHistory[0].
