plot two vectors simultaneuosly on the same axis?

Regards. I have 2 vectors. For example a=[2 4 3 6 7 8] and b=[7 5 2 4 4 1]. I wolud like to plot them both on x axis simultaneously, for exampe in order a=2,b=7,a=4,b=5... y axis is supposed to be 0 for vector a and 1 for vector b. is this possible to do? Thank you.

a=[2 4 3 6 7 8] 
b=[7 5 2 4 4 1]
x=[a ;b]
x=x(:)
y=[zeros(size(a)); ones(size(b))]
y=y(:)
plot(x,y)

THANK YOU VERY MUCH Azzi ! This is what I was looking for ! You saved me ! Best regards!

[Bojan]

just a question, this plot of yours is in order 2,1,2,1.... not in order 2,7,4,5...... as it is supposed to be from matrix. do you have solution for that?

[Azzi Abdelmalek]

The order is not 2 1 2 1, you can check by

disp(x)

Maybe you mean something else

[Bojan]

Jes, sorry. This is disp(x) 2 4 3 6 7 8 7 5 2 4 4 1

for me it should be 2 7 4 5 3 2 6 4 7 4 8 1

first value of vector a, then first value of vector b, then second value of vector a ..... and so on

and x axis is supposed to be long as sum of all values in both vector: 2+7+4+5+3+2+6+4+7+4+8+1 =53 cca

plot(a)
hold
plot(b)

[Bojan]

that is not what I am looking for. You should read better. Thanks anyway. Regards
