How do you guys get that sliding scale that measures weight loss on your profile?

Ok,  I know its a dumb question..... but I am not the savviest of computer people.

Can someone plse explain how I get that sliding scale thingie that shows starting weight, loss and goal?

At the top right, click on the picture icon, then go to settings > health tracker > "Go to Heatlth Tracker". From there, go to tickers and widgets > tickers > create new. 

Thank you so much!
