If I type
plot(x^2, (x,-2,2))
in sage, I get the expected plot, displayed as a png file by my default image viewer. If instead I put the line
plot(x^2, (x,-2,2)).show()
in a file test.sage and run
sage test.sage
from the command line, I get
Graphics object consisting of 1 graphics primitive
typed on the command line, but no displayed plot.
How do I display a plot from a script?
