How to set the linestyle and symbol in spectrum viewer

Hello everyone,
I am a fresh user of snap, today I used the spectrum viewer to watch spectrum of some pins (see the image in the below), but I don’t know how to set their styles in order to make the distinction among them. In fact, the help document showed the effect.Could someone give me suggestions?


Line style and symbol can be changed when you click on the filter symbol in the upper right.
You can open the Pin Manager (View/Tool Windows/Pin Manager) and change the colour of the pin. This will also change the colour for this pin in the spectrum view.
