Graph not plotted in SVW Data Trace Timeline Graph

Hi everyone,

I am using a NUCLEO-G474RE and I am following the "How to use STM32CubeIDE" Tutorial:

But in the final step when I call the SWV Data Trace Timeline Graph no graph is plotted. I follow the same steps as in the tutorial. I set the SWV frequency to 80 MHz. Also, I go to the SWV Data Trace Timeline Graph settings, enable comparator 0, fill in the Var/Add field with LED_State, the "Access" field to Read/Write and the "Generate" field with Data Value + PC. Then I click on "Start Trace" and on "Resume" icon for the LED to continue blinking. What am I doing wrong ? Thank you in advance.
