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 :)

Hi,
After looking in few old tickets, I can't correct the duplicate legend ?
c=3e8;h=6.626*(10^-34);k = 1.281*(10^-23)
k1=8*pi*h*c;k2=(h*c)/k
E(l,T)=k1*(l*1e-9)^-5*(1/(exp(k2/((l*1e-9)*T))-1))
f1=0;f2=E(l,3500);f3=E(l,4000);f4=E(l,4500);
params=dict(figsize=3,axes=False,fontsize=6,
frame=True,gridlines="major",
gridlinesstyle=dict(color="lightgrey",
linestyle="-"),
axes_labels=("$\Lambda[nm]$",\
"$E(\\Lambda)[KJ/nm$"),
legend_font_size=6)
f1=0;f2=E(l,3500);f3=E(l,4000);f4=E(l,4500)
b=plot([f2,f3],l,10,4000,legend_label="4000",
fill =[0, [0]],
fillcolor=['blue','green'],
fillalpha=1)
p=plot([f1,f2],l,10,4000,legend_label="3000",
fill={1: [0]},
fillcolor=["red","yellow"],
fillalpha=1)
d=plot([f3,f4],l,10,4000,legend_label="5000",
fill =[1, [0]],
fillcolor=['yellow','red'],
fillalpha=0.5)
v=plot(p+b+d)
v.show(**params)
Any help ?
Regards
Henri
