MATLAB: Legend for several matrix plots

Question

Hi there,

I'm trying to add a legend for my figure but the legend dose not match the matrix colour.

this is my code

figure
plot(Leftdata ,'K');hold on ;plot(Rightdata,'r'); % the size of Leftdata and the right data are  10coulumns and 101 rows for each. 
grid on
grid minor
legend('Left','Right');

Any Suggestion to figure this problem out!!!!

Your help is greatly appreciated 🙂

Thanks

Answer 1

Its not a single lines, its bunch of lines

#Edited

p1=plot(Leftdata,'K');
hold on ;
p2=plot(Rightdata,'r'); 
grid on
grid minor
legend([p1(1),p2(2)],'left data','right data')
