For the simple image provided, there should only be one contour detected, so extract out the … You need to set the extent of the imshow, so that the coordinates line up with those used in the contour plot. From the imshow docs: extent : floats (left, right, bottom, top), optional. The bounding box in data coordinates that the image will fill. The image is stretched individually along x and y to fill the box. So you could use:
