This option is used to analyze a specific cross section of a graph. This is particularly useful in analyzing any anomalies like peaks in traffic and drill down using various conditions.
To do this analysis, after selecting the criteria, you just need to select the required region by clicking the starting point of your choice and then the end point; this zooms the area that you chose.
Consider a graph generated using group by condition. If you want to analyze data for a particular minute, say 14:30 minutes, select the area between 14:00 and 14:38 (as per the graph in consideration) by following the steps below:
- In the graph, click the small dot on the graph which represents the starting time (14:00) under consideration. The area will be marked by a vertical line.

- Now click the small dot that represents the time that is preferred to be the end point (14:38); a zoomed form of the selected area of the graph appears.

Refreshing Data
It is possible to drill down data based on multiple criteria as well. For example, it is possible to check for requests to a specific API from a particular developer resulting in a certain error.
The refresh button can be used to re-fetch data from the server and re-plot the main representational chart. Notice the difference between Figure 1 and Figure 3. The end time in Figure 1 is 14:50; the data captured after that time is displayed upon clicking the Refresh 
button.
