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 is added every day.
Big dot "Unique count" = 2, small dot "Unique count" = 1
Thanks for the help!
