Hello all.

Is it possible to create a colour gradient between two linear boundaries
parallel to X axis, in any of these ways? A single colour ranging from light
to dark or three colours blending from green through amber to red.

Have tried inserting a filled rectangle and also importing an appropriate
image created in a drawing package. These are okay to a degree but can only
be placed in front of the chart covering the data or behind the chart and
out of sight.

What is needed is a means of visually indicating that all is well, or there
is something unusual happening, or that a dangerous condition has developed
when data plots into green, amber or red zones.

All suggestions would be appreciated.
