comparing two 3d scatter charts

Im new to matlab so excuse my lack of knoweldge. Im trying to compare two 3d scatter graphs. As you can see in the attached picture they are golf swings. im trying to find the best way to compare them

my matlab code is pretty simple for the output

data = csvread('new.csv',1); 
figure
hs(1) = subplot(2,1,1);
hs(2) = subplot(2,1,2);
x= data(:,2);
y= data(:,3);
z= data(:,4);
scatter3(hs(1),x,y,z, 'b', 'filled');
data1 = csvread('new3.csv',1);
x1= data1(:,2);
y1= data1(:,3);
z1= data1(:,4);
scatter3(hs(2),x1,y1,z1, 'r', 'filled');

[KSSV]

As you have the data in hand...you can find the difference between the data..isn't it eh?
