Bug: Heart Rate vertical axis all zeros when in Landscape

Connect iOS on iPhone 13 shows values on the axis when the phone is held vertically, but when horizontal and rotates to landscape, the rate axis goes to all 0s. Gavel Bike and Cardio do the same thing.

Side note, it would be just a nice touch to have the chart reflect colors of intensity like some of the other charts rather than all red.

Thanks
