## [SciPy-User] y limit and Bessel function plot to file

 Hello! I am new to SciPy, and with only a basic knowledge about Python. Using Python 3, I am considering the code in this page http://ctan.math.washington.edu/tex-archive/macros/latex/contrib/hybrid-latex/examples/example-04.pdfIt has been written for the Bessel function of the first kind. I am trying to adapt it for the Bessel function of the second kind. Being interested only in generating an output file, the useful lines in my case are just: #!/usr/bin/python3 import numpy as np import scipy.special as sp x = np.linspace(0, 15, 500) np.savetxt('example-04.txt',list(   zip(x,sp.yn(0,x),sp.yn(1,x),sp.yn(2,x),                                     sp.yn(3,x),sp.yn(4,x),sp.yn(5,x))),                                     fmt="% .10e") I have used the special function yn instead of jv. This is the `example-04.txt' output file: https://pastebin.com/xfCMQ4cH(first line is `0.0000000000e+00 -inf -inf -inf -inf -inf -inf'!) And this is the image generated using example-04.txt in LaTeX: https://imagebin.ca/v/4KKebbscyqSrHow to limit the output y range? I am interested in particular in y values between -2 and 1. With mathplotlib, it would be for example `plt.ylim((-2, 1))'. But what about scipy? Thank you anyway!
