Enhancement: Graphs

[kingofzeal]

I always find the charts displayed on the Statistics page to be highly confusing:

It seems that none of the graphs will show 0-value nodes. For example, the Hourly Plays graph for me has a lowest point of 1, and the X-Axis labels are in an inconsistent spacing (I'm seeing 9:00AM, 12:00PM, 6:00PM and 11:00PM right now, for example - I would expect it to be in constant 6 hour intervals). Plus, since it doesn't show "zero people watching in the graph", it looks like there is ALWAYS someone watching, which I know is not true. The Max Hourly Plays has a beginning time frame of September (!?) and is also highly inconsistent spacing on the X-Axis.

Somewhat related, the Monthly Plays graph has a lowest Y-Axis value of 300 right now. It helps show plays comparing month to month, but doesn't really give me a sense of scale overall that I would otherwise have if it was base 0.

The only graph that (I think might) behave as expected is the Daily Plays - it does have a minimum of 0 on the Y axis, but seeing as there's always at least one play every day it's hard for me to know if it would actually report a zero-play day or not.
