How to use pcshow in a gui (AppDesign)

Hi you all!

I would need to use pcshow in a GUI (app design). I tried something like this:

p=pcshow(app.UIAxes, [ptCloud.vertex.x ptCloud.vertex.y ptCloud.vertex.z], ptCloud.vertex.Scalar);

and this:

p=pcshow([ptCloud.vertex.x ptCloud.vertex.y ptCloud.vertex.z], ptCloud.vertex.GKI,'Parent',app.UIAxes);

but it doesn't work.

I also tried scatter3 to view my pointcloud:

p=scatter3(ptCloud.vertex.x, ptCloud.vertex.y ,ptCloud.vertex.z,36, ptCloud.vertex.Scalar,'Parent',app.UIAxes);

but it does not work either (the app crashes without giving me any error with this last one).

How can I pass the app.UIAxes? Is there a guide to learn by myself?

Thank you in advance
