I wish to visualize the movement of a data point throughout space across a period of time within MATLAB. However, the way I want my figure to display is such that only a single instant is plotted at any given time. That was easy, I simply created a for loop to update my 3D plot display for every set of coordinates (x,y,z) in my data. However, I wish to display 4 different viewing angles of this plot at all times. I am well aware of how to setup subplots within MATLAB, that is not the issue. My issue is getting all 4 of these subplots to execute simultaneously so that all 4 subplots are always displaying the same point in time.
I would appreciate if anyone could suggest how to handle this issue.
As requested, my code for a figure with a single plot is shown below:
datan = DATA; %data in form of x,y,z,a,b,c by column for row# of time points
tib=zeros(size(datan,1),12);
tib(:,1:3) = datan(:,1:3);
tib_ref=tib(1,1:3);
for i=1:size(datan,1)
tib(i,1:3)=tib(i,1:3)-tib_ref;
end
angle_to_dircos
close all
figure('Name','Directions (Individual Cycles)','NumberTitle','off')
for cc=1:2
hold off
for bb=1:10:size(tib,1);
scatter3(tib(bb,1),tib(bb,2),tib(bb,3),'green','filled'); %z and y axes are flipped in polhemus system
hold on
p0 = [tib(bb,1),tib(bb,2),tib(bb,3)];
p1 = [tib(bb,1)+10*tib(bb,4),tib(bb,2)+10*tib(bb,5),tib(bb,3)+10*tib(bb,6)];
p2 = [tib(bb,1)+10*tib(bb,7),tib(bb,2)+10*tib(bb,8),tib(bb,3)+10*tib(bb,9)];
p3 = [-(tib(bb,1)+100*tib(bb,10)),-(tib(bb,2)+100*tib(bb,11)),-(tib(bb,3)+100*tib(bb,12))];
vectarrow(p0,p1,1,0,0)
hold on
vectarrow(p0,p2,0,1,0)
hold on
vectarrow(p0,p3,0,0,1)

el = 0;
view(az, el);
