You can manipulate the histogram and its associated data in the following ways:
- Click anywhere within the histogram to focus on events that occurred at that particular time.
- Use the scroll bar at the bottom of the histogram to go forward or backwards in time.
- Hover over the histogram to change the cursor to a + sign. Click-and-drag the + to focus on a specific time segment.
- Click the <Back button to return to the previous histogram view (before you changed its aspect).
- Group events that have transpired within a certain time period — for example, 1 minute, 10 minutes, 1 hour, or 1 day.
