Hello!

I use elastic for to collect retail prices of goods.  
Many products do not change the price, and in the graph there is a mess, I want to remove from the schedule the products whose price does not change.  
Metric "Unique count" shows how many times the price has changed, but for this metric i can't make a filter.  
How can I display in the chart only those products for which prices have been changed?  
Data:  
productName: Bread  
Value: 20  
Data is added every day.

Big dot "Unique count" = 2, small dot "Unique count" = 1

Thanks for the help!
