Legend shows only one line type

I want to plot a figure with 6 groups of data, while in the plot, there are 6 different line types, but the legend always shows the same line type for all 6 groups of data. Could any one help me on this? Thanks!

Here is the code:

figure;

subplot(311);

hold on;

plot(X1(:, 3), X1(:,2)/X1(:,4), 'm','LineWidth',2);

plot(X2(:, 3), X2(:,2)/X2(:,4), 'r','LineWidth',2);

plot(X3(:, 3), X3(:,2)/X3(:,4), 'g','LineWidth',2);

plot(X4(:, 3), X4(:,2)/X4(:,4), 'm--','LineWidth',2);

plot(X5(:, 3), X5(:,2)/X5(:,4), 'r--','LineWidth',2);

plot(X6(:, 3), X6(:,2)/X6(:,4), 'g--','LineWidth',2);

%set(gca,'xscale','log');

legend('2.55','Honey Comb','3.57','5','1.88','Solid 1.88','Location','NorthOutside','Orientation','Horizontal');

title('X-axis Comparison');

ylabel('Transmissibility ratio)');

xlabel('Frequency(Hz)');

xlim([5, 250]);

grid on;

Can you please show the structure of X1 through X6.

Also how do you have 10 legends for 6 plots?

No line types are specified for the first three of your plots. The last three have the same line types.

It should work fine. See this example.

t=0:0.1:6;
figure(1);hold on;
plot(t,sin(t),'r+-');
plot(t,cos(t),'go-.');
plot(t,t,'b*:');
legend({'sin','cos','linear'});
