How can I open csv fille, sort and plot the data from it using GUI?
显示 更早的评论
I want to open a result CSV file, sort the rows according to one specific column and also plot a graph of two columns using GUI. I need to open the CSV file from different locations, so I also need to create a browse button also. How can I do it?
Thank you for your time and consideration.

The question is not clear enough. What does e.g. "open the CSV file from different locations" mean? Different servers, hard disks, folders, file names, over the network or on an offline backup drive? What is a "browse button"?

Given that you want to browse open '.csv' file from different locations using GUI, I would recommend using App Designer in MATLAB. As Stephen suggested you can use "uigetfile" function for this. Considering your requirements, you can follow these steps:
- Create an App Designer Project and you can browse open any '.csv' file using
[filename, pathname, filterindex] = uigetfile('*.csv');
csvfile = csvread(fullfile(pathname, filename));
- You can sort this '.csv' file using "sortrows" function, based on any column. Refer Documentation: https://www.mathworks.com/help/matlab/ref/sortrows.html
- Then plot the required columns using the "plot" function. Refer Documentation: https://www.mathworks.com/help/matlab/ref/plot.html
Refer to the attached example code for more details regarding implementation.

Using fullfile is safer than strcat(pathname,'/',filename), because it considers the file separator e.g. in 'C:\' .

Thanks Jan, I updated the answer with "fullfile".
