I've got a spreadsheet of different values of humidity & temperature etc etc.. for a computer datacenter that I'd like to graph. As you can see, I have one data point every minute, and I have 7,000+ data-points. When I tell Excel to graph this, its only using one data-point per day, versus doing a nice smooth curve, using a 'line-of-best-fit' thru all 7,000 data-points. How do I get Excel to draw me a MUCH smoother looking graph than the brick-pile I have pictured?? Thanks!
