How to load several and multiple files and plot them?

Dear community

I´m working with multiple data and I´d want to plot:

One specific column from every files v/s time.

Every file is according with one day specific.

How can I plot them by using a loop?

Thanks in advance!

I did this:

clc
clear all
% Specify the folder where the files live.
myFolder = 'C:\Users\jonat\Desktop\Clean';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.jpg'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
  baseFileName = theFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  num= xlsread ('C:\Users\jonat\Desktop\Clean');
  Voc = num (:,5);
  fecha = num (:,1);
  plot (Voc,fecha)
end

But I don´t get the plot of that. What can I do?

• xlsread() doesn't read jpg-files
• file name missing in xlsread ('C:\Users\jonat\Desktop\Clean')
