Superimposing a line plot onto an image

My code so far:

figure
plot(x, y); 
title('Angle'); 
xlabel('Horizontal Distance'); 
ylabel('Height');

I have an image but I don't know how to superimpose the image onto the plot.

Call imshow() to display your image first. Then put "hold on" and do your plotting.

[Ahmed Al-Sharif]

but the dimensions of the image don't fit the graph and it is very distorted when I use that.

And we are intended to guess what size the image is and what part of the image you want the plot drawn over ?

What are the dimensions of the image, and what is the range of x and y values you want to plot over it?
