ids=[1;2;3;4;5;6;7;8;9;10];
dx=[0.1;0.2;0.3;0.4;0.5;0.6;0.7;0.8;0.9;0.10];
dy=[0.01;0.02;0.03;0.04;0.05;0.06;0.07;0.08;0.09;0.10];
dz=[1;2;3;4;5;6;7;8;9;10];
figure;
plot(ids,dx)
%I need to plot dx,dy,dz w.r.t ids in the same figure with different colors like blue,red,black.

The command 'figure' is not necessary here. Also you can simplify your coding like dz=[1:10] or dz=[1:10]' if you want a column vector only - though for your purpose row or column vector does not matter.

if you check the documentation for plot() it gives good examples of what you can do
ids=[1;2;3;4;5;6;7;8;9;10];
dx=[0.1;0.2;0.3;0.4;0.5;0.6;0.7;0.8;0.9;0.10];
dy=[0.01;0.02;0.03;0.04;0.05;0.06;0.07;0.08;0.09;0.10];
dz=[1;2;3;4;5;6;7;8;9;10];
figure;
plot(ids,dx,'b',ids,dy,'r',ids,dz,'k')

'b'=blue 'r'=red 'k'=black 'y'=yello 'c'=cyan
etc. plot documentation will also give how to create line dashes, markers, etc.
