Hi,
Among the parameters that can be used in the Dashbord panel is “text”. Here I can enter the constant value I want.

I can also show the sum of the values I filtered in the table from the “metrics” section.

But there is no field where I can extract the values I have collected from the table from a fixed value. I can’t do this from Metrics. So how can I apply simple mathematical formulas like addition and subtraction to the data coming from the metric?
