Data Stream timeline

Graphical representation of the timeline of historical data from a data stream

How it works

Data Stream Timeline widget

This widget facilitates the visualization of value changes in a field over time.

Each timeline will display the name of the data stream along with the represented value, arranged as follows:

  • field
  • value

Grouping

By enabling the grouping of timelines, one can view all represented states on a single timeline (without separation).

When data are grouped, the representation of the timeline will change, displaying the value on the same timeline, and each bar will contain the following:

  • field

Summary

Data Stream Timeline General Configuration

Finally, those columns from which to extract data to display on the graph must be configured. A timeline will be generated for each of them.

For each piece of data, the following can be configured:

  • Alias a representative name for the column data on the graph
  • Color to distinguish it within the graph
  • Formatter tool is a tool that will process each piece of data, allowing for its modification and/or any calculation to ultimately display it on the graph. For example, it can convert numerical data into discrete data for representation.
  • Remove will remove the column from the configuration

Visualization
