why when i try to plot data on image, the plot exceed the image?

Hello,

while I designed a GUI software, i wrote a function which get as in put the handles of the gui. the function loads image and display it on a axes in the GUI with several plots on it (suppose to..)

now i dont know why but my plots just runs over the image or exceed it without displaying the image with the plots.. This is my code:

    axes(results_axes);
       hold on

     imshow(im);
     axis([xmin xmax ymin ymax]);
         hold on

    endplot(new_edge_points_array(:,2),new_edge_points_array(:,1),'o','MarkerEdgeColor','k','MarkerFaceColor',[0.03 0.96 0.65],'MarkerSize',10)
         plot(new_nodes_points_array(:,2),new_nodes_points_array(:,1),'o','MarkerEdgeColor','k','MarkerFaceColor',[0.97 0.41 0.04],'MarkerSize',10)

Example of the final result i want to get:

And this is what i keep getting:

it's probably minor mistake but i couldn't figure what it is

any help guys...Thanks!

Put this line in between the call to imshow() and plot():

hold on;

already did it, still not working? does it relate to the axis modification maybe?

Try this:

axes(results_axes);
hold off
cla reset;
imshow(im);
axis([xmin xmax ymin ymax]);
axis on;
hold on

then call the plots.
