Hi Andy I have been studying tableau for a few weeks but I am struggling to find out a way to get back the sql queries behind every visualization(graph) in tableau desktop. I hope you'll undestand what I am talking about .
In the data pane, click the down triangle and choose Hide All Unused Fields. The remaining fields are those that are used in the workbook. Then if you click the triangle again and choose Show Hidden Fields. The hidden fields will be grey. Those are the unused fields.
