I tried like in tutorial

sage: t = var('t')
sage: p1 = plot(cos(2*t) + 2*cos(t), (t,0, 2*pi), rgbcolor=hue(0.3))
sage: p2 = plot(4*cos(t) - cos(2*t), (t,0, 2*pi), rgbcolor=hue(0.6))
sage: show(p1 + p2)

and I can see a beautiful bicolour image of the 2 curves

But then impossible to find the touch combination (I tried a lot , q, Q, Ctrl D, exit, quit, escape.....) to exit the graph an return to sage command line

It depends on your png viewer. If you do not like this png viewer because there is no way to qui it, you can try to see the picture in your webbrowser instead, see http://doc.sagemath.org/html/en/refer... for more details. For example, you can type:

sage: viewer.png_viewer('display')

It is possible that your default viewer is imagemagick, in this case, you can right-cligk on the picture with your mouse and select Quit at the bottom of the column.

thanks for the link tmonteil but maybe show() does not use the sage function png_viewer ?

sage: png_viewer(app=None)

NameError: name 'png_viewer' is not defined
sage:

sage: sage.misc.viewer.browser()
'sage-native-execute /home/sage/notebook-browser'
sage:

show(p1+p2) do the same thing than pretty_print(p1+p2)
