Just to inform that I have changed 4 lines (I don't understand, but at least, I hate Lua) so that on the graph legend:
* the "/s" is removed. It was misleading as the interval is changing according to the selected button i.e. seconds, minutes, hours, etc.
* I was unable to understand at what scale is that graph, it should have a min and max and possibly being able to mouse hover for info at point X, like the built-in graphs. However, I don't know how to do that, therefore I just added to the Legend entry a min and max values. At least we can understand better that graph.
Edited %APPDATA%\Roaming\Factorio\mods\timeseries_fixfor110_0.3.5.zip\timeseries_fixfor110_0.3.5\control.lua
Line 134: changed to
local caption = string.format("%.2f [%.2f:%.2f]", value, min_y, max_y)
Lines 135-137: deleted, it is where the "/s" is added.
P.S. Actually, I have also did few more things :)
* Added the real MIN and MAX values as the original code was kinda choosing MIN to be always 0
* Added an average expectation for that selected period, basically if you select 1 minute period, it will show you the amount of items per minute. This is the most used metric across the wiki and other mods. For example, a full belt will show around 900 units per minute.
* Made the default period shown to be 1 minute, not 5 seconds lol
