You have file named legend.m please move it from the path or rename it.

thank you it is appear again but I have another problem, the legend doesn't show the three phi. it is show only one. how can I display the other two?

Please share the code you used to create this figure. If you look closely at the legend you will notice the second phi in the lower left corner. The way the legend looks, makes it look like you did some strange modifications in your code.

I used this code

subplot 221
 plot(time,Q1,'--',time,Q4,'.-',time,Q7)
 xlabel('time'), ylabel('joint angle [rad]')
 legend('\phi 1','\phi 2','\phi 3')
 axis([0 20 -0.7 0.7])

I can't reproduce this issue on my copy of R2015a with the code below.

%create a clean figure and some random data for debugging
figure(1),clf(1)
time=linspace(0,20,200);
Q1=0.6*sin(time);
Q4=0.6*sin(time+1);
Q7=0.6*sin(1.1*time);

subplot 221
plot(time,Q1,'--',time,Q4,'.-',time,Q7)
xlabel('time'), ylabel('joint angle [rad]')
legend({'\phi 1','\phi 2','\phi 3'})
axis([0 20 -0.7 0.7])
