Hello, you are connecting a constant block to the scope which is expected to work as shown only. But if you want to show the signal changing with time, you should connect to a time changing signal.

Hi wenchao zhang,
The Constant block, by default, has a constant sample time. For the model shown, constant sample time means that the output of the block is computed only once at the start of the simulation, as indicated by the scope. If you want to see the constant line in the scope, one way is to change the Constant block's sample time parameter to 0, i.e., continuous sample time.
