I don't think you'll find an inbuilt way of dealing with these units (in the
way you can with hours minutes and seconds), so I think your best bet would
be to put stones, pounds, and ounces in 3 separate columns, and then use a
helper column, perhaps in pounds, to combine the total, & then plot from
that column.

I'm sure this is very simple and i'm just being stupid but I can't seem to
format cells to accept imperial weight measurements and then allow them to
be
plotted on a chart. Any pointers would be most welcome.

thanks
