Sorry if this is obvious, but I don't have much experience with Excel. I have several years of data spread out over several sheets (a sheet for 2000, 2001, etc.). I want to add another sheet with graphs charting the trends in this data over time, but I can't figure out how to select data from one cell in multiple sheets. It seems like there should be an easy way to select cell C1 of every sheet, but I don't see it.
