i'm creating a graphic with contourf. And I wanted to correct the scale, by making X and Y referring to 2 files with the right scale.

Everything works, except the scale, it was not good so I want to say to my programm :

Use Excor.csv and Emcor.csv as abscissa and ordinate for the graphic. But for some reasons it won't work, Emcor and Excor are a multiple line * 2 coloms and the other files are multiple lines * multiples coloms files. I know it's a problem, so I added r=th meshgrid thing to correct it but it won't work.

Here is my whole program :

Everything that is in Black like that : Black is something that I added to correct the scale problem.

function plot_EEM_post_treatment(~)

addpath('C:\Users\antonin.gauchy\Documents\Antonin\Matlab Antonin\Script');

% Plot EEM post treatment data

% You have to manually select the folder that contains your data

% Make sure to select the right folder

folderPath = uigetdir('C:\Users\antonin.gauchy\Documents\THESIS\EEMs\Test_matlab\MARNE_0204','');

%load the emcor and excor data

emcor_data = readmatrix('C:\Users\antonin.gauchy\Documents\THESIS\EEMs\Test_matlab\Marne_0204\Res_RU\Emcor.csv');

excor_data = readmatrix('C:\Users\antonin.gauchy\Documents\THESIS\EEMs\Test_matlab\Marne_0204\Res_RU\Excor.csv');

emcor_values = emcor_data(1 : 150, 1)';

excor_values = excor_data(1 : 72, 1)';

% List every CSV file founded in the specified folder

fileList = dir(fullfile(folderPath, '*.csv'));

% Make sure that the code found the CSV

if isempty(fileList)

error('Aucun fichier CSV trouvé dans le dossier spécifié.');

end

% Counter for the number of CSV files processed

counter = 0;

% Loop to process each CSV file

for i = 1:min(length(fileList), 6)

% Import CSV file as a matrix

filePath = fullfile(folderPath, fileList(i).name);

data = readmatrix(filePath);

% Create X and Y coordinate grids corresponding to the size of data

[X,Y] = meshgrid(emcor_values, excor_values);

% Create a contourf plot

figure;

contourf(X,Y,data);

% Add a color bar

colorbar;

colormap(redwhiteblue(-1, 1));

h = colorbar;

% Specify the scale of the color bar

clim([0 1]);

% Add a name to the color bar

ylabel(h, 'Intensity (RU)');

% Add a title for the spectrum and labels for the axis

title(['Spectre de fluorescence 3D ', fileList(i).name]);

xlabel('λEx. (nm)');

ylabel('λEm. (nm)');

% Increment counter

counter = counter + 1;

end

% Loop through all CSV files found for plotting differences

for i = 1:6

% Import pairs of CSV files

filePath1 = fullfile(folderPath, fileList(i).name);

data1 = readmatrix(filePath1);

filePath2 = fullfile(folderPath, fileList(i+1).name);

data2 = readmatrix(filePath2);

% Calculate the difference

diff_data = data1 - data2;

% Create a contourf plot with the difference

figure;

colormap(redwhiteblue(-1, 1));

contourf(diff_data);

% Add a color bar and name it

h = colorbar;

ylabel(h, 'Intensity (RU)');

% Specify the scale of the color bar

clim([-1 1]);

% Add a title to the spectrum and axis labels

title(['Différence entre les Spectres de fluorescence 3D ', fileList(i).name, ' et ', fileList(i+1).name]);

xlabel('λEx (nm)');

ylabel('λEm (nm)');

end

end

I'm sorry but I'm a beginner to matlab and I've mostly used what I found online and didn't really create it myself so I 'm very counfused.

Hi, can you share the csv?

[Antonin]

Hello,

Sorry I haven't noticed you're message.

I've realised what I was doing was useless, sorry I'm doing it another way ^^'
