I'm not an expert on potentiostats, but notice that the test resistor on the little board that comes with the Rodeostat is only a 2 wire circuit....

I think Excel will let you do this. Just plot one of the graphs with its time axis; then add the second graph, with its time axis. Excel will locate the points properly. If you want to get fancy, you could write code in Python, or any other scientific programming language, that interpolates between time points and give you estimated graph points from one graph at the other graph's time points.
