Thanks! Do I have to group the data in time intervals in separate columns or
can I somehow sort them using only the 1 minute intervals?

You can use a pivot table to group times by such intervals.

I have a very large set of data (over 20,000 points) listed in minute
intervals. I'd like to be able to create charts using different time
intervals such as 5 minutes, 15 minutes etc. by using a pull down menu to
select the interval and have the graph make itself. Is this possible?
