I plot(x,y) a chart, for which I want to find two things: - all values of x for which y>some specified value, - all values of y for which y>some specified value.
How can I do it?

what have you tried so far? You already have `x` and `y` vectors, why not just filter them? – Imanol Luengo May 24 '16 at 07:41

Using numpy:
import numpy as np
x = np.linspace(0,25,101) #x: 101 values between 0 and 25
y = x**2/20
x[y>30] #filter output: [ 24.5 , 24.75, 25. ]
y[y>30] #filter output: [ 30.0125 , 30.628125, 31.25 ]
This assumes that you have access to the values which generated the plot.
