Graphics direction and order

Hi,

I don't know if you made it on purpose but graphics are reversed, they show the most recent downloads at the left instead of at the right. Perhaps you could add an option to select the direction.

Also, trying to order column doesn't work on statistics page.
If you can fix this, perhaps you could show the graph according to the order of the column, and then add an option in admin panel to select the default order (instead of the idea above).
