I recently downloaded 18 months of data in a CSV file and used Excel's built-in graphing to plot out just the stats that AdSense reports, with the addition of EPC.

Looking at trends over time is very interesting, especially if you do 7-day and 30-day moving averages. I can look back at points where I made changes and see what worked and what didn't. I can also get a better sense of what's normal than by looking at the daily stats.

For me, eCPM and overall earnings are what matter. Over the course of those 18 months, eCPM nearly tripled, but has now drifted back down to merely double. However, since impressions are up, earnings are still good. EPC has such a wide range on my site that I don't pay much attention to it.
