Convert 3DPointCloud into a plot XY (2D)

I need to transform a PointCloud to a plot of it from the XY plane, that is, from above. Thank you for answering

If the goal is to view the pointcloud from the top to see the XY plane, there's no need to replot the data.

1. To view a 3D axes from above, looking down on the XY plane, use view(2).
2. To remove the depth perspective, change the projection to orthogonal.

load("xyzPoints")
pc = pointCloud(xyzPoints); 
tiledlayout(2,2)
nexttile([2,1])
pcshow(pc)
title('3D')
axis on
box on

nexttile
pcshow(pc)
view(2)
title('2D perspective')
axis on 
box on

nexttile
pcshow(pc)
view(2)
title('2D orthographic')
axis on 
set(gca, 'Projection','Orthographic')
box on

However, if you really want to replot the (X,Y) values,

figure()
scatter(xyzPoints(:,1), xyzPoints(:,2), 10, xyzPoints(:,3),'.')
axis equal
grid on
title('2D scatter')
