Showing relative change in line chart

[Anonymous]

Hi,

I have a dataset with around 80 testvalues each day, and I want to plot each of them separately in a line graph to see the development. This I have achieved with a filtering.

In this line graph I also want to show the allowable relative change (both upper and lower, say +/- 5%), from day to day as two other lines. The idea is for me to be able to see when the testvalue changes too much. Therefore I want the relative change line to be shifted so it shows in relation to the datapoint of the previous day. Is there a way to do this?

Something like below, but without the circles and the gridlines.

I have a testID for each testvalue, as well as a field called testdate with the date.

Thank you in advance!

In general, you can create an additional measure or calculate column and then drag it to the value field.

Thank you!

I have tried that, but I can't seem to get it to relate to the previous day, only today.

Do you have tips to how I can do this?

@Anonymous ,

You can use DAX function like

PREVIOUSDAY(<dates>)
