I want to read a txt data file and plot it. I want to plot the first column of the data as the x-axis and the second column as the y-axis. Please tell me how to write the code.
Sorry if my English is not good enough.

Hi YK,
I wrote a simple code for you that only works if your txt-file consists of numbers-only. For this problems just use Google like 'How to read data from a txt file in Matlab' and you'll find your answer.
My data.txt only contains two columns of numbers.
YourData = readtable('Data.txt'); % Read your .txt-file
YourData = table2array(YourData); % Convert the data from table format to matrix
figure(1)
plot(YourData(:,1),YourData(:,2)) % Plot your data
xlabel('First column in your txt-file')
ylabel('Second column in your txt-file')

Hi.
Thanks for the quick comment.
I did the coding as in your example and it worked...
I'll be able to do better searches.
