Labelling mulitple traces on plot

Hi,
How would you go about automatically labeling each trace on a plot for the case where the values are automatically generated in a for loop
from this
to this
The labels either sitting on top of each trace or adjacent outside the plot preferably with transparent background.
my code:
for nn = 1:Kappan
cc = jet(Kappan);
figure(1)
loglog(dratio,G(nn,:),'.-','color',cc(nn,:))
grid on
xlabel('Length / Diameter')
ylabel('Gain')
legend('boxoff'),legend(c,'location','NorthWest')
hold on
end
hold off
Thank You,
Joe

Hi Thanks for the replies. c variable is to color each trace code below
c={}; for i=1:length(Kappa) c{end+1}=num2str(Kappa(i)); end
for nn = 1:Kappan cc = jet(Kappan); figure(1) loglog(dratio,G(nn,:),'.-','color',cc(nn,:)) grid on xlabel('Length / Diameter') ylabel('Gain') legend('boxoff'),legend(c,'location','NorthWest') hold on end hold off
% set(gcf, 'PaperPositionMode', 'auto'); saveas(gcf, 'test2', 'pdf') %Save figure export_fig('C:\Users\Joseph\Documents\Geophysics\PhD\Matlab', '-pdf','-painters');

figure(1)
for nn = 1:Kappan
loglog(dratio, G(nn,:), 'kd', 'LineStyle', 'none');
if nn == 1
grid on
xlabel('Length / Diameter')
ylabel('Gain')
hold on
end
text(dratio(end), G(nn,end), str2num(Kappa(nn)), 'HitTest', 'off', 'HorizontalAlignment', 'center', 'VerticalAlignment', 'bottom')
end
hold off
We need more information in order to generate the "wait" line and the infinity trace.

Yes, that's correct. Nan for the output of Gain if Kappa = Inf. So I guess I'll put an arbitrary large number for example 10^10 as Inf. And then how would you replace 10^10 on the text label with Inf?

if nn == Kappan
Kstr = 'inf';
else
Kstr = str2num(Kappa(nn));
end
text(dratio(end), G(nn,end), Kstr, 'HitTest', 'off', 'HorizontalAlignment', 'center', 'VerticalAlignment', 'bottom')
