How do I add non-keyboard characters to tick labels
Unfortunately, SigmaPlot doesn’t currently support mixed fonts within a single tick label. However, a fair number of non-keyboard characters are available for text. To view these, open the Character Map windows Accessory program, usually available under Windows|Accessories|System Tools.
1. Click the Advanced view checkbox, and set the Character set to Windows: Western. This is the set that SigmaPlot currently supports.

2. Highlight the character you want to insert, then click Select and Copy
3. Enter the text you want to use for tick labels into a worksheet column, inserting the copied non-keyboard character as desired

4. Now either plot the tick values as categories, or use them as the tick label source
