Graph date selection

[Chris]

Just a trivial request. If you get around to it, is it possible to add and the option to select dates for the graph to look at. Ie. 12-1-17 to 12-30-17. Or even a selective week in the past. They get kinda dense when you do a whole year or even 90 days. Thanks, love the site!
