Thomas, Gary et Peter You ALL correct, and Sun/Moon-Altitude is the way to go. Thus for a start, '$almanac.sun.alt' and '$almanac.moon.alt', and will be added to database for plot/graph.
Instead of "$almanac.variable.name", how to rename to something more meaningful as 'sun-alt = $almanac.sun.alt' and 'moon-alt = $almanac.moon.alt'? Where those statements can go? Apologies if awkward to rename as such, but there is a later logic for Belchertown skin to call its Graph routine.
