How do I change my health app from a bar graph to a line graph? I was using the Health App under iOS 9.2 - and in the 9.3 upgrade the Health App switched display from a line graph to a bar graph. 

I like the line graph better. I can't figure out how to get it back. 

My question is: How do I change my health app from a bar graph to a line graph?
Simply the answer is: you can not change because of the update
