I am creating an initial prompt page with Select Prompts to view one or all graphs on the dashboard. It is possible to also have additional prompts embedded in each page to change the type of chart (Line, Bar, Pie) or does this option have to be on the initial prompt page? Can I have both? Any feedback would be helpful.
You could probably do that by putting all of the graphs on the page then using render variables for each.
You can a) have prompts on report page just fine (and just to state the obvious - of course those will only work when running the report to HTML), and b) you can have multiple prompts for the same parameter just fine.
attached, find an example of how that would work, created against the Go Sales sample package.
