Hi there! 

IDL only supports the LaTex syntax for graphics. It does not work for data storage or display in the IDL console or IDL Command Line. 

You will want to use the BYTE/STRING functions together to create the special character....like...

PM_SYMBOL = string(byte(177))

177 is the byte value for the plus/minus symbol. Other symbol values can be found here: http://www.utf8-chartable.de/unicode-utf8-table.pl?utf8=dec&unicodeinhtml=dec

Now that +/- is stored as a string, you can use it like:

freq=['23.8 GHz','31.399 GHz', '50.299 GHz', '52.8 GHz', '53.595 '+PM_SYMBOL+' 0.115 GHz'] 

Hope this helps.
