I have 3 pivot charts being controlled by a slicer that changes the week ending date. On the chart I have "Impressions" on the Primary Axis and "Clicks" on the secondary axis.
What I would like is for the scale of the Secondary axis to automatically adjust when the slicer is changed, so that it is always equal to 2% of the Primary axis. This way, I know that when the Secondary line is above the Primary line we have hit our target.
Does anyone have any ideas on how to achieve this?
