Thnak you Dave - of all the alternatives, this gives me the result I want
best. What I want to be able to do is enter production figures in a table,
and see if the maximum daily production is exceeded, when a range of
products are made. Your method allows the graph to be any size I want, and
to move anywhere in the data (in the window below) without changing the
table's position.

I'm sure this could also be done with VBA (to automate your method), so I'll
give that a go....

Thanks again,

Rob
