[sage-support] **legend
Hi, I have params=dict() which works well, I am trying to look the same way with lgd= ? like lgd=dict...something ? I didn't find answer This way works but I have to put a variable (q, here) but when I change it can change too ? q.set_legend_options(loc=2,font_size=6,shadow=False, back_color="lightcyan") show(q,**params) If there is way ?

Following William's hint, I came up with a workaround. The first solution
I found at https://stackoverflow.com/a/45664729 didn't work on .sagews
files, so combining that with https://stackoverflow.com/a/44100805,
I ended up with the following. Do
tell me if there's a better way!
from IPython.display import SVG, display
def svg_show(pic, *args, **kwds):
"""
Display the plot 'pic' using svg (rather than png). If we are in
Jupyter (ie. IPython)
we need to do this explicitly. Otherwise we can use the default show()
function.
"""
try:
get_ipython
pic.save('temp.svg', *args, **kwds)
display(SVG(filename='temp.svg'))
except:
show(pic, *args, **kwds)
r = var('r')
svg_show(plot(2*r- r^2, r, 0,1) + plot(1, r, 1, 2), ymin=0.5)

[sage-support] Re: duplicate legend
Two years ago I made this pic in a texmacs sage session, but
unfortunatly sage doesn't work anymore with texmacs, I am reproducing it
but I have the legend problem, otherwise I think it should be even nicer
with new sage 8 xx .
Thanks for any help :)

Re: [sage-support] Re: duplicate legend
I found the problem it's because I use to put two functions (f1,f2only
one needed f2) apparently it works but I have to correct my graphs.
