There are eink devices out there running Android and allowing access to the system preferences, namely rooted devices. Those can give you exactly that graph. Here is an image of the graph as of my device:

But as others noted due to the technology difference the percent value of the display usage does not make any sense here. It is not very helpful without context for "normal" Android devices but here you can't draw any meaningful consequences from it. "Mobilfunk-Standby" (cellular standby) doesn't make much sense also.

Plus this was just taken after unplugging. Maybe I can take another photo in a few days with more useful data, according to my usage (which differs from using it only for reading, that was the whole point of rooting).
