How to delete the axes coordinate in Matlab GUI?

I want to make a Matlab GUI program. When i use the axes to display the
image, there are the axes number around the axes.
How to delete it? so my GUI program will display the axes without any
coordinates around the axes.
here is my code for display an image in axes.
axes(handles.axes16);
handles.image_gray = image_gray;
imshow(image_gray);
guidata(hObject, handles);
And here is the axes coordinates that i meant.
