I know how to annotate a chart area, but, that text ends up on the main chart area. I often need to add a footnote at the bottom of a chart. (In excel, I just add a text box, reducing the size of the chart, if necessary, to create some room under the chart.) So, how do I do this in Tableau? Thanks
You can show and edit the worksheet caption - Worksheet > Show Caption.
Alternatively, you can use text boxes with your worksheet in a dashboard.
