Hello @OriAlpha,
I assume that you wish to project your 3D plot on a 2D plane.
You can follow the code below to project your plot on XY, YZ or ZX plane
theta = linspace(0, 2*pi, 100);
x = cos(theta);
y = sin(theta);
z = theta;
% Plot the original 3D data
figure;
subplot(2, 2, 1);
plot3(x, y, z, 'b', 'LineWidth', 2);
xlabel('X');
ylabel('Y');
zlabel('Z');
title('3D Plot');
grid on;
axis equal;
% Project onto the XY plane (ignore z)
subplot(2, 2, 2);
plot(x, y, 'r', 'MarkerSize', 10);
xlabel('X');
ylabel('Y');
title('Projection onto XY Plane');
grid on;
axis equal;
% Project onto the XZ plane (ignore y)
subplot(2, 2, 3);
plot(x, z, 'g', 'MarkerSize', 10);
xlabel('X');
ylabel('Z');
title('Projection onto XZ Plane');
grid on;
axis equal;
% Project onto the YZ plane (ignore x)
subplot(2, 2, 4);
plot(y, z, 'm', 'MarkerSize', 10);
xlabel('Y');
ylabel('Z');
title('Projection onto YZ Plane');
grid on;
axis equal;
This is the output the code generates
