Thank you for your question Braillebud!
When TGs exist in a Nemeth context, the use of uncontracted words as labels is permitted, but our TG experts agree that the labels in your samples should be keyed and the single-word switch indicator should not be used. This will ensure “cleaner” graphics that allow the reader more space to investigate the graph itself. Additionally, in the case of these images the key will likely fit on the same page.
Attached are a screen shot and BRF file showing some examples that may help illustrate these concepts.
