Learn more about contour, axes, reverseFirst, load in the image, the generate (x,y) pairs for each intensity in the image. This is done with meshgrid. Once you do this, use scatter to plot each point assuming z = 0 and make the colour of each point the actual intensity seen at the image coordinate. However, you will only see this in a 2D perspective as scatter is naturally 2D.If flipping only the y axis is what makes it correct then I would suggest you plot your data correctly in the first place so that it is consistent. Flipping the y axis is just a matter of whether you have the origin at the top or the bottom, but the data will move with it, if you just change the YDir setting of the axes

The code example is not good. The first two lines are not needed because variables xand y are not used. subplot(1,1,1) is also not necessary and axis(..) has no effect because it comes before imagesc. If it came after it would actually change the part of the data that is shown, so better not using it at all here. –
