3D Plot of 2D sim

I have the following code. The code works for me now and it provides a 2D plot, however I am trying to plot a 3D plot. So an example would be like this:

Example

Do you have sugesstions to do this in MATLAB? Thanks

Code:

%Start setting up constants
% Compute the cyclotron frequency and radius (Larmor radius)
omega = (charge .*B(3)) ./mass; 
rL = v(2) ./omega; % try v(2) as well since initial v is the perp velocity to B


X = zeros(n,3); % initialize an array of zeros with size nx3 for positions


for time = 1:1:n
     %compute the t vector
     %compute the s vector
    % start the Boris algorithm:
    % First half E acceleration: generally for E =/0 ande B =/0
    % First half B rotation
     % Second hald B rotation 
    % Second half E acceleration 
    % Finally update position
    
end

% plotting 
figure;
plot(X(:,1),X(:,2),'k','Linewidth',2); hold on;
set(gca,'TickLabelInterpreter','Latex','Fontsize',14)

ylabel('$ y / d_{\rm p} $','Interpreter','Latex','Fontsize',14); 
xlabel('$ x / d_{\rm p} $','Interpreter','Latex','Fontsize',14);

Hi Lujain,

After setting v = [0 1 1] to provide some initial z velocity,

figure(2)
plot3(X(:,1),X(:,2),X(:,3))
grid on

and note that if you put the mouse cursor inside the window and click on the symbol with the circle enclosing the cube, you can rotate the plot with a click-hold mouse.

Hello David!

Thanks a lot, this does work!
