I have data obtained from pinhole scanning. The data consist of 4 columns x, y, z and intensity.I want to plot the beam intensity in yz plane to see how the beam looks like. The problem is that I have got 240 graphs which is the number of points along x axis and it is hard to see the full shape of the beam. Is there any other way to represent the data and plot it in yz verses intensity. I appreciate your help. Here is the code i have written.

close all;
clear all;
x = [2850:2.5:2850+2.5*239]; % scan along x axis start with 2850 and increment by 2.5 micron (240 points)
y = [1200:2.5:1200+2.5*159]; % scan along y axis start with 1200 and increment by 2.5 micron for 160 points
Path = 'C:\.5um_Z-900_to_700_Aper10um\SCAN__XYZ__2017_12_11_15_58_30_mUmU_no12_240x160_step2.5um_Z-900_to_700_Aper10um';
Data = zeros(240,160,16);
k = 0;
for j = 1:16
   for i = 1:160
    k = k+1;
DataTemp = importdata([Path '\lineScan (' num2str(k) ').txt']);
Data(:,i,j)= DataTemp(1:240,4);
end   
end 
for z=1:240   
DATA = Data(:,:,z);
subplot(4,4,z);imagesc(Data(:,:,z)')
end

在 MATLAB Online 中打开

files = dir('*.txt') ;
N = length(files) ;
figure
hold on
for i = 1:N
    i
    data = importdata(files(i).name) ;
    x = data(:,1) ; y = data(:,2) ; z = data(:,3) ;
    c = data(:,4) ;
    plot3(x,y,z)
end
