I have the following legend:
legend('4C_{ACTIVE} - PI_{ACTIVE}','4C_{FIXED} - PI_{FIXED}');
I want to put overbar over the letters PI (not on the subscipt or anywhere else). Can someone suggest how to do this?
Thanks in advance.

Thanks Walter. It works but when I use this the formatting is changed. Can you please also suggest how to remove italics from the legend and make it bold. I tried but it still looks the same.
Thanks,
S

Perhaps
h = legend('$\bf{4C_{ACTIVE} - \overline{PI}_{ACTIVE}}$','$\bf{4C_{FIXED} - \overline{PI}_{FIXED}}$')
