I would like to read in a spreadsheet of data in columns and be able to select which column the graph displays. I have (hopefully) attached what I have so far as a couple of images and the xls file. Any ideas?
The transpose works but you need to understand something more basic about the index array function. You wired a control to the 'row' input. If you want to extract a column, you need to wire your control to the 'column' input. The transpose is an unnecessary operation.
