@elukey I seem to have lost the ability to un-pin items from showing up in the graph. It's hard to describe, but using the colored squared seen in this screenshot, I could filter items in/out of the chart without using the formal filter function. This was incredibly handy when looking at large breakdowns like the one shown. I'm hoping it's a config setting that you can change.

@JKatzWMF I got a similar report from SRE as well, I believe it is due to this:
Simplified Line Chart legend
This time we removed something from turnilo. Legend is now simplified - it is read only and all values are derived from your split and filter definitions. No more out of sync bugs. (#595) (5d0fbd6)
So it seems a choice that upstream made :(
