Over Time chart (OTV)¶
The Over time chart helps you identify trends and potential gaps in your data by displaying, for both the original modeling data and the derived data, how a feature changes over the primary date/time feature. It is available for all time-aware projects (OTV, single series, and multiseries). For time series, it is available for each user-configured forecast distance. See also Understand a feature's Over Time chart.
Using the page's tools, you can focus on specific time periods. Display options for OTV and single-series projects differ than those of multiseries. Note that to view the Over time chart you must first compute chart data. Once computed:
-
Set the chart's granularity. The resolution options are auto-detected by DataRobot. All project types allow you to set a resolution (this option is under Additional settings for multiseries projects).
-
Toggle the histogram display on and off to see a visualization of the bins DataRobot is using for EDA1.
-
Use the date range slider below the chart to highlight a specific region of the time plot. For smaller datasets, you can drag the sliders to a selected portion. Larger data sets use block pagination.
-
For multiseries projects , you can set both the forecast distance and an individual series (or average across series) to plot:
For time series projects, the Data page also provides a Feature Lineage chart to help understand the creation process for derived features.
