I have 5 curves on the same xOy, how can I calculate an average curve for all 5 ?
calculating average points from 5 points does not seem to give correct result.
I don't understand what you mean. Do you have 5 points or 5 curves. And what do you mean by "an average curve"- average in what sense?
I am sorry it is 5 curves. In my second post, I thought I could pick many points on all of those curves then calculate the average but it didn't turn out correct as expected. Do you know how to draw an average curve ?
