[0.17.54] [Minor] Production graph X-axis units not obvious for 250h and 1000h

[robot256]

I saw my 190-hour game stopped at "7.8" in the 250h graph and didn't know what it meant. I found this bug report where it states the units are switched to Days in the 250h and 1000h views, which explains the graph. But unless you read it on the forum or sit down with a calculator, the user will not expect a button labeled "250 hours" to produce a graph labeled in days.

I'd like to suggest that you either put a unit label on the graph or change the labels on the buttons from "250h" and "1000h" to "10d" and "40d". That way the user will know what to expect on the graph.
