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
