This works as I expected:
for i=1:100
hold on;
plot(i,i^2);
drawnow;
end
Ploting the points as they come in the same figure.
This on the other hand, doesn't:
for i=1:100
hold on;
plot3(i,i^2,sqrt(i));
drawnow;
end;
Since it does not show a 3d plot of the points, it only shows the projection of them in the xy plane. Somehow the hold on
statement messes up with plot3.
How can I obtain results that are analogous to the 2d case when using plot
, in the 3d case, when I have points in several 3d locations?
I've tried to make this question concise, if you believe I haven't explained it well enough for a satisfactory answer please say so in the comments.
Your code correctly plots a 3-D curve. All you need to do to see it is add
view(3);
anywhere in your code.
Additionally, one hold on
command is sufficient (i.e. you don't need to repeat it in every loop iteration).
