Hi @beyondkeke

What is wrong in this image? Sorry to ask

Also what version are you using? There were a bunch of tooltip improvements in 8.1.1 and 8.1.2

Thank you for your answer!  
I used the V7 version.  
My problem is that the line graph values do not match the current values.  
It looks like the value of each line graph is the sum of all of the above.  
Until the last one.  
There was no such bug in the V8 version.

can you include a screenshot? It sounds like `stacking` is turned on and is aggregating your time series…
