Plotting 3D graph with 3 different set of coordinates

HI there I need some help please,

%Node 1
x1=-419;y1=-341;z1=30;
z2=15; z3=0;

hold on
plot(x1,y1,z1)
hold on
plot(x1,y1,z2)
hold on 
plot(x1,y1,z3)
hold off

There is a problem with the plotting it says in the matlab file, i also like to ask if i have another set of coordinates that wants to be plotted into the same graph can it be done, meaning this 3D Graph has 6 different coordinates but the only difference is the z direction.

When you are plotting single point, you need to use marker.

%Node 1
x1=-419;y1=-341;z1=30;
z2=15; z3=0;

hold on
plot3(x1,y1,z1,'s')
hold on
plot3(x1,y1,z2,'s')
hold on 
plot3(x1,y1,z3,'s')
hold off

You can plot whay you want using scatter3. Read about it.

%Node 1
x1=-419;y1=-341;z1=30;
z2=15; z3=0;

x = repelem(x1,3,1) ;
y = repelem(y1,3,1) ;
z = [z1;z1;z3] ; 

scatter3(z,y,z,1000,z,'.');

Thanks but I got the idea from another source already I use the plot3 method with hold on and off method, thanks anyway

Oh wait is the same method haha sorry thanks for the idea too
