You can change the axis direction using the axis properties: 

set(gca,'YDir','reverse') % starts at the top of the figure
set(gca,'YDir','normal') %starts at the bottom of the figure

  • it is not working the y-axis is still the same ... see this pic http://s9.postimg.org/i08ink1cf/image.png – roger1 Jun 19 '13 at 16:43
  • I missed that you were plotting an image. Use 'normal' instead of 'reverse' to have the axis start at the bottom of the figure. – Molly Jun 19 '13 at 16:49
  • hi ... there is a big problem ...when i put your code and then get snapshot ,,Picture becomes inverted,,,how i can fix this problem – roger1 Jun 19 '13 at 18:14
  • I need more information. Are you using snapnow? How are you publishing the output? By inverted do you mean upside down? You should probably ask a new question. – Molly Jun 19 '13 at 18:35
