This widget tracks and displays distinct count of all categories in the selected parameter (Distinct values by field). X-axis (horizontal) represents time and Y-axis (vertical) represents distinct logon count. Each data point on the chart represents unique logon count at a specific time. All the data points are plotted and connected with a line to track the maximum and minimum number of distinct logons.
For example: If the Distinct events count line chart widget is customized as follows:
Interval set to 1 hour.
Distinct values by field is set to User name.
The widget displays number of unique users logged in to all events for the time duration of 1 hour.
