One way would be to use images for the lines instead of draw graphics and
set the blendLevel of the "lines" to a medium-high value.  As the lines are
overlapped, the "stack" will appear darker.

Alternately, you might use draw graphics with simple color changes: if your
stack has a light background use a light color when a low number of lines is
present and then darken the color for higher number.
