I have 10 sets of data which I have to analyze. The data represents a change in voltage over time and I want to come up with an "average" curve to represent the 10 sets of data. The problem is that the time index for each data is different so I can't simply average the voltage. Is there any method which I can use to solve this problem? I've attached an image of the graph with 3 sets of the data so you understand what I'm dealing with. Thanks in advance.
