I have some .txt files containing 2 columns of number (x,y) of each point identified by the x,y coordinates. I should find a way to produce an image file (the format is not important, it may be a .jpg for example) in which the x, y coordinate are identified of the .txt file (x and y coordinates). How can I concert the coordinates into an image?

Thanks!

在 MATLAB Online 中打开

    A = importdata('file1.txt') ;
    B = importdata('file2.txt') ;
    x1 = A(:,1) ; y1 = A(:,2) ;
    x2 = B(:,1) ; y2 = B(:,2) ;
plot(x1,y1,'r') ;
hold on
plot(x2,y2,'b') ;
saveas(gcf,'myimage.png')
