imcrop image with hold on plot

Does someone know how can I crop and image and a plot to obtein both the result in another figure, I tried with getframe and frame2im but it pixels the image too much.. Does someone know another option?

And I need to do it in comand line automaticalle, not using the figure option. In rect you can see the rect i would like to use in the imcrop function.

I = imread('cameraman.tif');
rect = [71.5 92.5 101 76];
figure, imshow(I);
hold on
plot(1:200,'LineWidth',2)

Thank you

You ave not cropped your image. Question is not clear.

Sorry, I thought the question was clear, let me try to explain it to you with an example. Imagine I have a function that returns a figure containing the representation of an image and with hold on some data from the plot function. What I need is to cut out that figure which is extracted from the previous function

I = imread('cameraman.tif');
rect = [71.5 92.5 101 76];
figure
subplot(2, 1, 1);
imshow(I);
croppedImage = imcrop(I, rect);
subplot(2, 1, 2);
imshow(croppedImage);

That's not what i'm asking... i need to crop it with the :

plot(1:200,'LineWidth',2)

plot() does not do cropping. Not sure why you think it does. plot() will just overlay a line/curve onto the image. Cropped images need to remain rectangular. If you want to blacken rows beyond a certain row, you can do that though

for col = 1 : 200
    grayImage(col:end, col) = 0; % or whatever intensity you want.
end
