Drawing line between elements with same values in a 2D matrix

Hello community! I have a 2d Matrix:

A = [1 2 3 4 5 6;1 3 5 4 6 9;4 1 3 8 7 5];

it looks then like

1     2     3     4     5     6
1     3     5     4     6     9
4     1     3     8     7     5

Now I want to draw lines between elements with value = 1 and value = 3 and mark these values on the line.

Besides, in the plot, the columns of the matrix should be labeled in form of a x axis by

x = 8:13;

and the rows of the matrix should be labeled in form of a y axis by

y= 2:0.1:2.2;

Can someone please help me on this? Thanks a lot!

clf
A = [1 2 3 4 5 6;1 3 5 4 6 9;4 1 3 8 7 5];
y = 2:0.1:2.2;
x = 8:13;
[X Y] = meshgrid(x,y);
[oI]= find(A==1);
[tI]= find(A==3);
figure(1),hold on
plot(X(oI),Y(oI),'rx')
plot(X(tI),Y(tI),'bx')
%gen lines
for ind = 1:length(oI)
   for jind = 1:length(tI)
      plot([X(oI(ind)) X(tI(jind))],[Y(oI(ind)) Y(tI(jind))],'g')       
   end
end

Thanks, but this is what I got

Could you please may be do some modifications?

shouldn't you be doing the modifications? Based on your description that's what you described. You'll have to put in some effort.
