The ability to view a reputation graph for a specific time frame is no longer working in Chrome:
A user is supposed to be able to select a specific time frame for viewing in the large graph by clicking in the small overview and dragging the blue box to cover the desired time frame. Adjusting the blue box no longer has any effect on what is shown in the large, detailed graph.
I have reproduced this behavior across multiple Stack Exchange accounts. I am using Chrome 49.0.2623.110. The graphs work corerctly in IE 11.0.9600.18125.
Here is a .gif animation of me clicking around in the overview graph without the large graph updating:
