I want a correct logic of my code.
Also, I want the operations on my two plots i.e.
1. error of two plots
2. difference curve
3. correlation.

3 operations are
1. to calculate error of the two plots
2. to calculate difference of the two plots
3. to calculate correlation of the two plots

Why can't you get the difference by just subtracting the variables from each other? I am assuming they are of the same size
