Use hold on
figure
hold on
plot(rand(10,1),'r')
plot(rand(10,1),'b')
plot(rand(10,1),'g')
legend('data1','data2','data3')

plot([rand(10,1), rand(10,1), rand(10,1)])
legend('data1','data2','data3')
Use colororder before calling plot to have your prefered colors.
The vectors v1, v2, v3, in plot([v1, v2, v3]) must be column vectors, all with the same dimension
