Is this possible:

I'm looking for a way to proportionally fill a cell based on the contents.
For example, if the contents of four rows are:

..8
..75
..5
1

then the contents of these cells are 4/5, 3/4, 1/2, and completely
full....(either top to bottom or left to right).

Right now I'm using a stacked bar graph, but lining up the axes of the graph
on top of the the cell gridlines is quite a challenge and very time
consuming. I'm not optimistic, but thought I would put this question out
here to check.

Many thanks in advance.
