Plotting multiple input CSV on 3D graph
显示 更早的评论
Hello,
I have made a succesfull 2D plot of a single CSV file.
Now I was wondering if I could use the same code to plot multiple of these files to create a 3D plot.
Is there a simple way of just telling matlab to import all CSV files found in the directory, and use them chronologically where first drill is dataset #1, 2nd #2, etc?
Each CSV contains datapoints of multiple voltages/currents/accelerations measured from a CNC machine.
So it would show the Voltage, Current, Power, etc on the z-axis, time on the x-axis and # of drill on the y-axis.
Thanks!

You need to proceed something like below:
csvFiles = dir('*.csv') ; % get all csv files
N = length(csvFiles) ;
m = 100 ; % this is the row numbers in each csv file
Voltage = zeros(m,N) ;
Current = zeros(m,N) ;
Power = zeros(m,N) ;
for i = 1:N
data = csvread(csvFiles(i).name) ;
Voltage = data(:,1) ; % assuming first column is voltage
Current = data(:,2) ;
Power = data(:,3) ;
end
surf(Voltage, Current, Power)

You are not saving the data into the initalized matrices.
%clear everything
clc
close all
clear all
%compare files in 1 graph
%declare folder containing the files
d = uigetdir(pwd, 'Select a folder');
csvFiles = dir(fullfile(d, '*.csv')); % get all csv files
L = length(csvFiles); %amount of csv files
m = 250000; % this is the row numbers in each csv file
%create variables
UH_V = zeros(m,L);
IH_A = zeros(m,L);
IV_A = zeros(m,L);
A_G = zeros(m,L);
%read data from files
for i = 1:L
data = readtable(csvFiles(i).name); %read table of every file
%delete first column and first 3 rows
data(:,[1]) = [];
data([1,2,3],:) = [];
UH_V(:,i) = data(:,1); % assuming first column is voltage
IH_A(:,i) = data(:,2);
IV_A(:,i) = data(:,3);
A_G(:,i) = data(:,4);
end
% surf(UH_V, IH_A, IV_A)
