Hello guys,
Have an issue here.
I have a large array of numbers, X and Y values.These are coordinates of 9 curves on the same x-axis , so the X values are repeating (433 X values repeating 9 times), what I need to do is to sum Y values for each X value separately. and then plot it (bar plot would be great), I need to see at which place the sum ofY values cross he 0 axis ( the Y values are both possitive an negative).
Thanks in advance!
