How to plot lines between points
显示 更早的评论
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 ?

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.
