No data with GSR sensor serial monitor

I have this version of arduino … -usb-cable
linked with a grovehat via an analog port.
I pasted the code in the sketch and executed but I can’t see nothing in the serial monitor. Why?


Grove hat supports only A0 port please modify the following line your code as follows

const int GSR=A0;

Thanks and Regards

already done and no change was detected. I also deleted the buzzer code to save space.
I also installed the driver for the board.
I made a new sketch with an easy serial.print(“hi”); and it doesn’t work. So the problem could be at the base.

SOLVED. Noobish mistake. I didn’t upload the thing. How can I show the plot of the data? The plotter doesn’t seem to work
