What did you do?

I want to put 12 hosts aggregations on the graph to display.
Host field use regex "/.*/"
Item field use "CPU Load"

What was the expected result?

used function "aggregateBy(2m,avg)" to aggregate "CPU Load" in one line

What happened instead?

I should have 2 lines one of them is aggregated by 12 hosts and the another one is only displayed one host But these two lines overlap.
It looks like the regex "/.*/" don't work.
I don't know it's a bug or something else make this happened
