Stats for More than a month

Hi,

First of all, this is a fantastic plugin. Thanks for putting it together.

One of the main reasons I bought Pro version is for the stats/charts. As of now the chart is limited to one month – beginning from 1st of every month. So its kinda odd that you cannot see stats on the first of every month. It would be a nice feature to be able to see last 30 days by default with optional range selection.
