Hi,

To some extent it depends how many times the lines cross. If it's just the
once then you can use area charts to provide the shading.

This may help if the used one line as a base line.

More complex lines may require a coded solution.

Can the overlap portion(s) of two lines in a chart be shown in a different
color, without having to manually draw a shape? I would like to show the
areas where Line A is above Line B as red, and the areas where it crosses
below in blue - is it possible to do this without manually drawing in
shapes?
