Example of drawing on a View using onDraw(Canvas).
Default to 0-100 and 50.
Put three examples up.
Landscape better for showing three.
README please
First try at drawing the actual reading.
Drop in the rounded border, although we can't(?) use it yet.
Apply bordered style, works in portrait.
Juggle layout a bit. Still hardcoded for now, may become styleable.
Draw rectangle not two floating lines. Draw 3 tick marks.

The tick marks show that the numbers are being drawn on their
baseline not vertically-centred; next is to get the font ascender
and move the text down to the midpoint.
