Hello all,
How can I make the plots of each time-history to be centered at zero using code? I usually manually add or substract the required amount from my data. As-per the example below. I wish to automate the centering of my plots.
Original code :
plot(t,x,t,x2,'r')
Revised Code (not the best solution)
plot(t,x-0.038,t,x2-0.003,'r')
Original:
Revised:
Thank you in advance

Is the offset you are subtracting the mean of the values in the corresponding arrays? If so, just subtract the means:
plot(t,x-mean(x),t,x2-mean(x2),'r')
As above is a tad better than manually inserting the means as magic numbers.
