I have a solution of y and x as a function of time.

I want to shift the values of y by subtracting it with the first value in the array of y, and then perform of 1D line plot.

Is there a syntax to write it COMSOL like "y - y(1,1)"?

Any help or suggestion.

Thank you

PS: I can export the data and then plot in MATLAB but I want to do it in COMSOL

Oh yes, see https://www.comsol.com/support/learning-center/article/Examples-of-the-withsol-Operator-33781:

y-withsol('sol1',y,setind(t,1))

is a general form, such that you could not only subtract a value from your first solution (here assumed to be called 'sol1', but check), but from other studies too. This extracts the first time indexed value of y. Try it out...
