What are the top hours

[Stives]

Dear Splunkers,
running version 9.3.1 and I would like to perform a search in which I would like to identify what are the most common hours trucks have been visiting my site location.
My search query is following:

| addinfo
| eval _time = strptime(Start_time,"%m/%d/%Y %H:%M")
| addinfo
| where _time>=info_min_time AND (_time<=info_max_time OR info_max_time="+Infinity")
| search Plate!=0
| search Location="*"
| timechart span=1h count by Plate limit=50

Like this Im able see trucks visiting location by time in a span.
How to continue to display what are the most common hours during which my trucks visiting locations.
Thank you

Can you provide an anonymized sample of what this search displays and an example record of what you want the final output to be?

Also you should define what is your synonym for “common hours”?
