now I would like to use the sage-shell too. I use the **-ipython -pylab** options but when I try to draw anything, using for instance:
x=randn(1000); hist(x)
or
f = plt.figure()
plt.plot(range(10),range(10))
plt.show()
nothing happend. Nevetheless if I ask for plt.savefig('blahblah.png') I have the image on my disk...
what did I messed?
very strange...
sage: f1 = lambda x:1
sage: f2 = lambda x:1-x
sage: f3 = lambda x:exp(x)
sage: f4 = lambda x:sin(2*x)
sage: f = Piecewise([[(0,1),f1],[(1,2),f2],[(2,3),f3],[(3,10),f4]])
sage: f.plot()
with the **-pylab** option alone works, it seems that **-ipython** is to blame; any idea?Fri, 21 Jun 2013 04:22:45 -0500https://ask.sagemath.org/question/10268/open-a-plot-window-from-sage-console/Answer by kcrisman for <p>I have sage notebook working perfectly on my Mac (including plots of course).
