Time Series Charts

Time series charts present a series of data points collected over a specified reporting period. The x-axis plots time and the y-axis plots data points.

The following time intervals affect the content of a time series chart:

Reporting period
The period during which data points are collected for presentation in a chart. For example, a time series chart might present aggregated data points collected over a 24-hour period.
Granularity
The period during which data is considered for generating a single, aggregated data point.
For example, suppose you want to find the average bps for a network device within a reporting period of one day. You could calculate a single data point consisting of the average of all data points collected within that 24-hour period. Or you could apply a finer granularity by calculating the average of data points collected within a smaller time period, such as 1 hour, over the course of the 24-hour period. If you apply a granularity of one hour for a reporting period of one day, the chart would contain 24 aggregated data points. For information about the granularity periods that are supported for a given reporting period and report type, see the table in the Data aggregation topic.

Types of time series charts

Time series charts include:
  • Resource Time Series (RTS). A collection of data points for a single resource over a given reporting period. Data aggregations in a Resource Time Series chart are time aggregations.
  • Group Time Series (GTS). A collection of data points for a group of resources over a given reporting period. Data aggregations in a Group Time Series chart are spatial aggregations.
  • Advanced Group Time Series (AGTS). A data set consisting of both time and spatial aggregations.
  • Trending and Forecasting Time Series. A collection of data points collected over a trending and forecasting period rather than over a reporting period.
  • Multi-Resource Time Series. A collection of data for multiple resources (maximum of 100) and for multiple periods.
Note: The type of chart displayed depends on the type of chart style assigned to the report. If no chart style is specified, the default is a line chart.
