Just wondering how i get rid of the data point off the graph shown. Any help is much appreciated.
x_1 = [0 1 2 3];
y_1 = [0.031 0.2236 0.431 0.578];
errx_1 = 0.1*ones(size(x_1));
erry_1 = 0.001*ones(size(x_1));
errorbar(x_1,y_1,erry_1,erry_1,errx_1,errx_1,'b*')
hold on
plot(fittedmodel1)
hold on
x_2 = [4 5 6 7 8 9 10];
y_2 = [0.645 0.684 0.711 0.731 0.749 0.765 0.779];
errx_2 = 0.1*ones(size(x_2));
erry_2 = 0.001*ones(size(x_2));
errorbar(x_2,y_2,erry_2,erry_2,errx_2,errx_2,'b*')
hold on
plot(fittedmodel2,'m')
legend({'','cos(2x)','','son(t)'},'Location','southeast')
xlim([0 10])
ylim([0 0.8])

Specify the line objects to include in the legend by supplying their handles.
h1 = plot(fittedmodel1);
h2 = plot(fittedmodel2,'m');
legend([h1,h2],{'cos(2x)','son(t)'},'Location','southeast')
Do you mean sin(t)?

Glad I could help. Be aware that if you add additional objects to the axes after calling legend() they will be added to the legend.
