Using the Histogram Feature

To use the Histogram feature:

1. Log in to BLAZE.
    
2. Select the View tile.

   The histogram shows the number of occurrences in a unit of time. 
   
   For example, eight vehicle objects in one minute.
   
   
   
   

6. Click the Plus (+) or Minus (–) icons to zoom in and out and change the timescale. 
   
   In the example below, we see the daily general activity, and at a specific moment 234 vehicle objects in 22 minutes.
   
   
   
   Multiple object types present during an interval are listed and color coded differently. 
   
   The example below counts people, faces, and vehicles.
