rectangle percentage fill

 

I am trying to create a rectangle as a sort of meter that displays how much of the daily range the pair has moved.

For example, if the pair has moved 75 pips today out of its daily 14 ATR of 100, then the rectangle would be 75% coloured in.

Any ideas how to do that? Do I need to create 2 rectangles and change the width?

How would I go about specifying a width of say 47%?
