How to put string on the x axes and plot more than 1 graph?

Hello everyone, I get a problem to plot 4 graph in 1 figure and x axes must be string like this :

 x axes  y1  y2  y3  y4

   A    1   2   3   4
   B    3   4   1   2
   C    4   1   2   3
   D    2   3   4   1

Thankyou for the answer .

Are you sure you are constructing a plot and not a table?

Or are you saying that what should be associated with the first trickmark on the x axis is the string

x axes

    A
    B
    C
    D

all as one unit?

a=[ 1   2   3   4
  3   4   1   2
  4   1   2   3
  2   3   4   1]
plot(a)
set(gca,'xtick',1:4,'xticklabel',{'A','B','C','D'})
