Comment (by jdemeyer):
I also don't get the following doctest changes:

Here we show how to plot simple pictures. For more advanced
aplications use list_plot instead. To see the resulting picture
use ``show(P)`` in Sage notebook. ::

sage:
P=desolve_rk4(y*(2-y),y,ics=[0,.1],ivar=x,output='slope_field',end_points=[-4,6],thickness=3)
