Get statistics as time series

Retrieve statistics data as a time series. The from and to parameters are rounded down and up according to the granularity. This means that if the granularity is set to 1h, the from and to parameters will be rounded down and up to the nearest hour, respectively. If the granularity is set to 1d, the from and to parameters will be rounded down and up to the nearest day, respectively. The response will include explicit 0 values for any missing data points.
