Hi,
First of all, for your problem, I would recommend you to use App Designer instead of GUIDE as recommended here.
You need to break your problem into components.
- Select multiple csv files, and read them individually.
This can be done using readTable as it provides flexibility to specify the number of header lines to be ignored, which is 2 in your case.
[filename, path] = uigetfile('*.csv','Select csv files','MultiSelect','on');
x = {}
for i = 1:length(filename)
data = readtable(fullfile(path,filename{i}), 'HeaderLines',2);
x{i} = data;
end
big_table = vertcat(x{:});
app.UITable.Data = big_table;
I created this in AppDesigner, button push callback function. This will help you read multiple csv files, ignore 2 header lines of each file and output the relevant data in a 'table' format. All these individual tables can then be merged into one big table, and used directly for displaying.
- In your plotData callback, you can add your code to read the data from the UITable and plot it, using the code you have mentioned in your question.
Hope this helps!
