Clickable History graph to select month or quarter

In the Summary section, It might be handy to make the graph clickable in order to select which data to display as opposed to the toggle arrows. I don't know how easy that is to do. Obviously it's easier for the graph to remain static, but it might be a nice addition. It was pretty intuitive for me to attempt to click on one of the bars in the graph to change data. When that didn't work, I then looked for another way, despite it being pretty obvious. I'm not sure if that would be everyone's reaction.
