How to get the activity power in Simvision

Dear all,

I'm using simvision to analysis activity power.

Here is the command I used:

read_vcd -vcd_module dut -module top -activity_profile -start_time 10000 -end_time 30000 -simvision ../../i303_tb/test/TOP_IO_Power_exper/POWER_EXPER.vcd 

  So, how can I see the activity power in the waveform?

In other words, I want see the active power during the signal changed in waveform.

Thanks for the help ^_^.
