I have 2 sets of data from the same experiment recorded with different methods. The results are 2 graphs describing the same but with some differences. To find those differences I want to subtract the graphs so that I can have a visual representation of where the differences are located.
The problem I have is that the first method has a "X resolution" of 10 data points per second, but the second method's resolution is not constant, sometimes its 7, sometimes its 15. Because of this I can’t just subtract the arrays, since they are not the same length.
Is there a way to do this?
