i have 3 coordinates x,y,z.. i have to plot it using plot3. my x,y,z coordinates gets updated in a for loop. i want all the points to get plotted in one plot using the default line style 'Solid line'. but ican't get it.i can only able to get using other line styles like 'o' , '.'.. Can anyone please help me with it???

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()

instead of saving it in the vector, is there anyway to do it using handle

Yes, and the easiest way to do it using the handle is to use animatedline() to create the object and then use the methods to add points.

i have tried it.but animatedline is also not working for this case i have done as you said , but it is not working

Show us how you're trying to use animatedline. I just tried a simple example and it worked fine for me.
h = animatedline(NaN, NaN, NaN);
view(3)
axis([-1 1 -1 1 0 10]);
for z = 0:0.1:10
addpoints(h, sin(z), cos(z), z);
drawnow
end

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.

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
