I am using Visio 2013 and I am trying to properly add an index to a variable c' (label of a square element) so that it is below the '. This is possible in Word 2013 using an equation, however I cannot copy and paste the equation to Visio (it's invisible there). If I just subscript the index, it is behind the ', not below:
I tried adding equations as and object in Visio using Microsoft Eqution-Editor 3.0, but it doesn't work with that either.
Any suggestions?
