I have the following CSV Data I used Excel Charts to plot the Data
I want to compare these Data with other Data, in another word i want to comapre 2 curves and check the similarity between them
in my case $$ y = f(x) = \text{Value | x=Time} $$
i found the following formula
$$ \% \text{ error} = \frac{\sum{||{f(x)-g(x)}}||}{\sum\sqrt{(x_{i+1}-x_{i})^2+(y_{i+1}-y_{i})^2}} $$
is this Formula correct ?
are $x_{i} \text{ and } y_{i}$ the Value or simply the Indices that are in my case Time?
what if the both functions have different x or Time but they have/follow the same trend ?
i'm using python for programming

in this case instead we use integration we sum the data because we have only points
$$v_{mm} = \frac{1}{stop-start} \sum{f(x)^2} $$ $$v_{cc} = \frac{1}{stop-start} \sum{g(x)^2} $$
$$\text{error % } C = \sqrt{M^2+P^2} $$
