Monthly Statistic and Data usage would be nice

[JFKnippschild]

Is your feature request related to a problem? Please describe. I like to have a monthly statistic on data usage as shown in the attached picture. You see the data usage total in upright corner. You have daily graphs which honor the heavy use times 7 am to 11 pm in light blue and the rest in grey. The legend gives you hint on the daily usage.
