Hi Wongsagorn,

It is my understanding that you are getting an error while loading data from MAT file.

Could you please check your MAT file and its name. From the screenshot that you have shared, I could see that executing the below command didn't return any field names:

>> open 'teststruct'

After executing the above command, it should show the field names as current, time, and voltage as shown in the below image,
