I have a series of values: here's a sample:
Val1(s) Val2(s) abs(difference)(s) 0.0347251 0.0405869 0.0058618 0.0705912 0.0772789 0.0066877 0.1117939 0.096079 0.0157149 0.156394 0.1282144 0.0281796
Rather than showing the difference as a value, I would like to represent it relative to the magnitudes of val1 and val2. My first thought is a ratio but that doesn't make sense, because it could be diff/val1 or diff/val2 or diff/avg(val1,val2) but none of these seem like an appropriate way to go about this.
How should I represent the difference so that it is easy to see the magnitude of the difference relative to the values?
