All, I have stumbled upon a (for me) unexpected behaviour of axvspan().
import matplotlib.pylab as plt from numpy import * x = arange(1000) y = 0.2*sin(0.02*x) ax = plt.axes() plt.axvspan(250, 400, facecolor='g', alpha=0.2) plt.plot(x,y) plt.show() The displayed y range is -0.2 to 1, while from the sine amplitude I would have expected -0.2 to 0.2. The expected y range can be obtained by omitting the axvspan() call and also if it is called *after* plot(). Is this the desired behaviour, especially in view of the dependence on the call order? __version__ is 1.1.0 Cheers, Joachim ------------------------------------------------------------------------------ Achieve unprecedented app performance and reliability What every C/C++ and Fortran developer should know.
