I am using 24 columns in the Drag-able Column 2D Power Chart to represent temperatures throughout the day.  For example from 12:00 AM to 8:00 AM all columns have value 18, from 8:00 AM to 5:00 PM 15, and from 5:00 PM to 12:00 AM 20.  The three ranges described are interpreted as three periods, sleep, away, and home, respectively with different desired temperatures for each.  The user is able to adjust columns up or down and therefore adjust the desired temperature for any given hour.

My questions are as follow:

1. Is there a way to adjust the entire period, so all the columns from say 12:00 AM to 8:00 AM, by dragging any of them?  It doesn’t make sense to just adjust one column in this scenario.
2. Is there a way to drag a column horizontally?  This would in essence extend the period.

The idea is that this would give a user a very simple way of adjusting the desired temperature for any given period as well as adjusting the lengths of periods.

Thanks
