ye I agree having the dataprocessing in fetch or wherever might be
more appropriate ... especially for those who want to use the data
elswhere ...

as for improving the graphing ... as you may have noticed from my
websites ... graphics is one of my favorite passtimes ... that is
why I spend so mucht thought on it ...
