Can time be used as both the x variable and the y variable when
creating a scatter plot?

I want to determine the correlation between the time one of our company
TV commercials is aired versus the time of day that we receive phone
calls. My objective is to determine which commercials generate the
most calls. I am entering the times as "10:30", "1:15" etc.

Thanks!

Yes, time can be used on both axes of a XY Scatter chart. (Date and)
time are stored as numbers. Dates are whole numbers starting with
1/1/1900 being 1. Time is the fraction part stored as 0=midnight and 1
=next midnight. So, 0.5 would be midday.
