Below code is example of matlab help document.
x = -pi:pi/10:pi;
y = tan(sin(x)) - sin(tan(x));
plot(x,y,'--rs','LineWidth',2,...
                'MarkerEdgeColor','k',...
                'MarkerFaceColor','g',...
                'MarkerSize',10)



You can describe axes on your image.
data2 = imread('map.tif');
figure(1);
iptsetpref('ImshowAxesVisible','on');
imshow(data2); %'colormap',bone(0)
set(gca, 'XTickLabel', {'a', 'b', 'c', 'd', 'e', 'f'} );
set(gca, 'YTickLabel', {100:100:700} );
xlabel('Longitude');ylabel('Latitude');
