How to plot lines between points

I Have a matrix of routes (11x11)

1 5 46 1 0 0 0 0 0 0 0

1 41 10 40 73 13 27 1 0 0 0

1 31 75 49 30 16 58 14 28 53 1

1 68 36 20 55 9 47 35 1 0 0

1 7 34 24 57 64 1 0 0 0 0

1 4 45 25 50 17 52 1 0 0 0

1 59 11 32 26 56 19 51 33 18 1

1 2 44 42 43 65 23 62 22 29 1

1 48 37 70 72 61 71 21 38 6 1

1 76 69 3 63 74 1 0 0 0 0

1 39 12 66 67 60 15 54 8 1 0

This means that the vehicle will go from 1 to 5 to 46...and return to 1 again. There are 11 different routes.

I have plotted already

for i=1:N

pltx(i)=z(i,2)

plty(i)=z(i,3)

pltz(i)=z(i,1)

end

n=numel(pltx);

plot( graph(1:n,1:n),'LineStyle','none','Marker','d','XData',pltx,'YData',plty);

z(Nx3) is a matrix with the coordinates of each point.

Now i would like to plot a line that would follow the order in the matrix routes connecting the points with z coordinates.

The outcome im looking for is this:

or something close. Any ideas on what else i would need to add to my code to make it work ?

@KonVak

N=76;       %number of points
z=80*rand(N,3);        %point coordinates
routes=[1	5	46	1	0	0	0	0	0	0	0;
        1	41	10	40	73	13	27	1	0	0	0;
        1	31	75	49	30	16	58	14	28	53	1;
        1	68	36	20	55	9	47	35	1	0	0;
        1	7	34	24	57	64	1	0	0	0	0;
        1	4	45	25	50	17	52	1	0	0	0;
        1	59	11	32	26	56	19	51	33	18	1;
        1	2	44	42	43	65	23	62	22	29	1;
        1	48	37	70	72	61	71	21	38	6	1;
        1	76	69	3	63	74	1	0	0	0	0;
        1	39	12	66	67	60	15	54	8	1	0];
routes(routes==0)=1;  %changes 0s to 1s to make plotting simpler
scatter(z(:,2),z(:,3),'d',"filled"); %plot points
a = num2str([1:N]'); labels=cellstr(a);
text(z(:,2)+1,z(:,3)+1,labels,'fontsize',8);  %label each point
hold on;
for i=1:11
    plot(z(routes(i,:),2),z(routes(i,:),3))
end

Try it. Good luck.

Thank you, that worked more than fine.
