The following linked post was incredibly helpful for me but I would like to know how to obtain the indicies of the brushed data. I'm not sure why, but the size of Pos and the size of brush are different. I want to obtain the indicies in Pos of the brushed data. Thank you.
Handle = plot3(Pos(:,1),Pos(:,2),Pos(:,3), 'o');
axis equal;
view(0,90)
brush on
Select the required data and run the following to get the brushed points:
xd = get(Handle, 'XData');
yd = get(Handle, 'YData');
zd = get(Handle, 'ZData');
brush = get(Handle, 'BrushData');
brushed_x = xd(logical(brush));
brushed_y = yd(logical(brush));
brushed_z = zd(logical(brush));
figure, plot3(brushed_x, brushed_y, brushed_z, 'o');
