You cannot plot with solid line style if you only plot one point at a time.

You should save your data in vectors and plot3() the entire vector after the loop.

If you need the line to update during the run for animation purposes, then have a look at animatedline()

在 MATLAB Online 中打开

my x, y,z is not a function of z.. my x,y,z are the three different coordinates of an object. for example:

x=10;y=8;z=13;

then gets updated after some time (for every t=1:10) randomly...Now i have to plot these and connect all these points after time t.

在 MATLAB Online 中打开

x = 0; y = 0; z = 0;
h = animatedline(x, y, z);
view(3)
for K = 1 : 100
  x = x + randi([-1 1]);
  y = y + randi([-1 2]);
  z = z + randi([-2 1]);
  addpoints(h, x, y, z);
  drawnow();
end
