How to make a tracker that counts the occurrence of an activity without using front matter?

What I’m trying to do

Hey, I’m trying to use the tracker plugin to build a habit tracker for “Exercise” but I don’t want to use front matter. I’d like the plugin to recognize if I have “- Exercise” in the text of my daily journal and show the occurrences on a monthly chart.

Things I have tried

searchType: text
searchTarget: '-[x] Exercise'
folder: 01 - Areas/Life/Journal/Daily
datasetName: Exercise Log
month:

this is what I’ve tried, and I get the error message, “no valid Y value found in notes”.

What am I missing here?
