MATLAB: 3d Animation of a point

3d plots

i have a excel file consist of x,y and z displacement of a point for particular frequency. is it possible to show the 3d animation of a point from its initial position to a position where it will get displaced for particular frequency. i want to create gui which will import displacement from the excel sheet. is it possible to create gui?

MATLAB: I have 3 columns of numerical data and I want to plot a surface. How to do this? I am willing to send the file and code. If I could get a coded response, I would be elated! Thanks.

clc; clear all ;
[num,txt,raw] = xlsread('ScaleData.xlsx');
x = num(:,1) ; 
y = num(:,2) ;
z = num(:,3) ;
X = reshape(x,[],3) ;
Y = reshape(y,[],3) ;
Z = reshape(z,[],3) ;
surf(X,Y,Z) ; 
shading interp ;

[num,txt,raw] = xlsread('Book1.xlsx') ; 
x = num(:,1) ; 
y = num(:,2) ; 
w = num(:,3) ; 
plot(x,y)
hold on
% remove the nans 
idx = isnan(x) ; 
x(idx) = [] ; y(idx) = [] ; w(idx) = [] ;
scatter(x,y,w+20,w,'filled')     % 20 is added to 20, it can be changed
