Put overbar and subscript multiple times

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.

h = legend('$4C_{ACTIVE} - \overline{PI}_{ACTIVE}$','$4C_{FIXED} - \overline{PI}_{FIXED}$');
h.Interpreter = 'latex';

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,

Perhaps

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