Been 2 years since I’ve done anything in Grafana so I’m rusty. Pulling series of decimal values from a sql db. Each day for say 7 days has a series of 48 values. Need to display for each day the % of values that are below a certain threshold. We use this to help gauge the quality of a product.

Finding the values to calculate from is easy. Not sure how to best get the percentage.

hello,
What is your database ?
What is 25th percentile, you mean 25 % and 75 % quartile ?.
for that you have to count your series index ordered by value .
