Need to draw a polygon on the figure from scatter3d function.

%I have several points with theirs 3D coordinates (attached xlsx file). I read these values from xls file with uigetfile. Then I create coordinate system to view these coordinates in figure.

% I need to draw a polygon with these points for calculating area and volume associated with these coordinates. For doing this, I need to get these points coordinates when I click on them and draw polygon with these points which clicked on.

here the example,

[FileName1,PathName] = uigetfile('*.xlsx','Select the excel file')

[num,txt1,raw] = xlsread(FileName1)

points_id=raw(:,1)

x_cell=raw(:,2)

x=cell2mat(x_cell)

y_cell=raw(:,3)

y=cell2mat(y_cell)

z_cell=raw(:,4)

z=cell2mat(z_cell)

 figure(1),scatter3(y, x, z, 'b*');grid on;

 text(y, x, z, points_id);   %do this after the plotting or labels will not show up

title('COORDINATE AXES')

xlabel('Y')

ylabel('X')

   zlabel('H')
