Call to attention when user falls below user defined acetone threshold

In the old app (v1), we allowed the user to define certain thresholds that would change the coloring of the measurements

We should support a similar concept to this in the new app

I can see a few ways to get there. Any one or combination of the below (or an idea not listed):

• Changing coloring of the measurements view

• Changing coloring of the graph view. Can imagine setting thresholds then fading colors in and out according to some gradient. Then as I’m approaching my threshold colors start to fade into that threshold color and continue to change color more intensely as I cross further and further into the threshold. Could also show a dotted line on the graph that indicates where the thresholds are

• Alert/notify the user after taking a measurement that they are below their configured threshold
