Filling in color in a box based upon a variable .

[Dan C]

I would like to fill a shape (box) with a colour based upon a specific
number. For example, if a number is .25 then I would like to show the box 25%
full by having the bottom 25% filled with a colour. The colour would fill
more or less of the box based upon a variable entry. I would like to use a
slider tool to select this amount. Can anyone help with how to do this?
