I'm Using Matlab 2015b and have a real-time application with target scopes running on a Speedgoat target machine. Some of the target scopes are correct with the signal name of the input being displayed above the scope. Where i have multiple signals going into a scope i use a MUX block and name each signal into the block. This sometimes works but some target scopes however do not display the signal name above them, instead they display a number. I've checked that the signal going into the scope is named and all appears correct. Is there something i am missing?
