Statistics Page: Improvements and Additions

In case you didn't catch it at the bottom of any page, there's a link to the statistics for SG:

http://www.steamgifts.com/stats

Some pretty interesting things to see there.

Improvements: change the range on the Y-axis for "Value of Gifts Created" and "Odds of Winning Per Entry" as both are horribly skewed due to just a couple data points. (mass developer giveaways) Making this adjustment would allow for a more granular view of the trends over time, where as now the lines are mostly flat due to the outliers. I assume the widget automagically chose the range based on max values, but there should be a way to manually set the range.

Addition: Add another chart showing the breakdown of non-contributors/contributors. Could be a graph like the existing ones, with one line as total members and another line as contributors. Maybe a third line showing average contributor value. ($ amount on the Y axis, left side of graph)

Any one else have ideas for the stats page or am I the only one who has checked it out?
