Hi,

let k is variable. For example, if k=3, then I will have speed1 speed2 speed3.

How can I automaticly generate one plot with all speeds and also different legend for each one?

Thanks

ps:t=0:0.01:100

t=0:0.01:100
speed1=cos(0.01*t);
speed2=sin(0.05*t);
speed3=cos(0.1*t);
y=[speed1;speed2;speed3];
plot(t',y');
for k=1:size(y,1)
  leg{k}=sprintf('speed%d',k);
end
legend(leg);

great....thank a lot ...I also generated acceleration with leg2...in the future, in guide, I would like to add check boxes. Count of check boxes will be based on number k, with possibility to show only checked speeds...it will be difficult?

Hi, color for leg1 is blue, green, red and color for leg2 is again blue, green, red. I need generate different legends, so there is not possible to repeat any color. Can you help me please?

This is my code

for k=1:3;
             leg1{k}=sprintf('speed_%d',k);
             leg2{k}=sprintf('acceleration_%d',k);
         end
    legend = legend([leg1,leg2]);
