Missing legend entries in plotyy

i'd like to plot multiple data lines in a plotyy graph. But it is not showing the correct lines

The TC is a variable. The grpah is plotting all variables but my legend shows only the amount of variables as 1 string.

How can this be solved?

n is the amount of TC graph i want to plot:

n=input('amount of plot TC : ');

figure(1)

T_pl=[T TC(:,1:n)];

ax=plotyy(t,T_pl,t,radiation);grid on

legend( 'Setpoint Temperature',...

'Measured Temperature',...

'Setpoint Radiation',...

'Measured Radiation',...

lgnd(1:n,:),...

'Location','SouthEastOutside')

Use yyaxis instead of plotyy.

Instead of using plotyy(x1,y1,x2,y2)

use

yyaxis left

plot(x1,y1)

yyaxis right

plot(x2,y2)

Then call legend.
