What exactly does "convert it to graph" mean? Do you want to rotate the image or the data?

在 MATLAB Online 中打开

I = imread('grrp.jpg') ;
I1 = rgb2gray(I) ;
I1(I1>200) = 0 ;  % convert white background to black 
[x,y] = find(I1~=0) ;  % get the non zeros 
plot(x,y,'.r') ;
set(gca,'ydir','reverse')
set(gca,'xdir','reverse')
