Having an issue with some pivotcharts?

[jpgrimes22]

I have a pivotchart with a drop down box "Time" with all 1440 minutes in a
day on the x-axis. I would like to be able to select 60 minutes on the drop
down box at a time for each hour in the day without having to select each
minute at a time. Is there any way to solve this issue?

In the pivot table, group the times by Hours and minutes. Then, in the
pivot chart, select the hours that you want to show on the chart.
