No setting that I know of.

I'd hide all the charts first:

Hide graph1
Hide graph2
Hide graph3
Hide graph4

'and you'd still have to show

if optionone then
Show graph1
elseif optiontwo then
....

Is there some kind of parameter I can set on each chart to hide them
by default? and if so, when the user changes graphs, would the
previously unhidden graph become hidden again automatically?
