Hello   This is to inform that i am currently facing an issue with assigning a superscript 'a' to the treatment header in a bar graph. There are 4 treatments and the last treatment column of the graph contains this superscript 'a'.   I have tried with the following symbols but nothing has worked. '~', '^', '(*ESC*). Can you kindly suggest how to program so as to represent the superscript. Thank you    ... View more
