I need to be able to choose "YTD" or " QTD" for an application, and then have the charts on the sheet reflect the appropriate date ranges for those values. I was going to try and use ValueList and literals (e.g. ValueList('YTD','QTD')) in a filter pane, but when I do that, the selection doesn't seem to go anywhere, because it's not in the data model. Any suggestions?
