A quick way is to segment by hour of day at both the Campaign and Ad Group levels.
You can find the Segment drop-down under the Campaign and Ad Groups tab.
From here select, Time -> Hour of Day
Be sure to take your Ad Scheduling into consideration and be aware of the date range you are viewing.
Hope this helps!
Hi Budi, there are two different ways of doing this, and it depends on what you are looking for.
The first one is on either Campaign level or Ad group level. Just click on Segment > Time > Hour of Day.
The second one is on Dimensions level.
Going for the Dimensions level you can add much more filters.
