On the Chart Customization page, would like to see the ability to overlay one chart with another. For example, overlaying the calorie consumption data for the past month with the fat consumption data for the past month.
My bad. That capability already exists. There is an option for both a left Y-axis and a right Y-axis in the add chart section in Trends. Looked right at it, but it didn't register. Too much coffee, I guess!
