What command did you use to show the image?

Try imshow(), and set the xdata or ydata properties to meet what you want.

im=imread('Spray1.png');
imagesc(im);
ylim([0 100]);
set(gca,'XTick',[])

More: All ticks 0,10,20.....100

im=imread('Spray1.png');
imagesc(im);
ylim([0 100]);
yticks([0 10 20 30 40 50 60 70 80 90 100])
set(gca,'XTick',[])
