So, I have a chart I created. X axis comes from column A and Y comes from column D. I want to create a second graph that is identical to the first but now I want the Y to come from column G. Is there any sort of find and replace that I can use in a chart? I'm also going to have to recreate these same charts on another page in the workbook. Total I'm going to have 9 charts, each with 20 series... that's a whole lot of clicking in Excel's somewhat painful interface. The shitty format of my data (sar -d, modified to include the timestamp on every line instead of the first of a series, sorted by disk name and then time stamp) makes it painful to use the wizard. I'm ending up with rows 1-50 for series 1 (one line in my graph), 51-100 for series 2, etc up to 20 different series. In column A, rows 1-50 are identical to 51-100 (new disk, same times).
