You can ask anything you want.
If what you want, though, is to understand how she feels about you, you may not get that from the chart. Charts are largely for record-keeping, legal reasons, memory jogs. I don't think the chart is going to capture their whole experience and what if you want is to peek inside their brain, I think it would be less than satisfying to just ask for a chart.
If you don't want to go so many times a week, don't. Unless you are court-ordered to do it or something, there is no reason to.
