I don't have the time to improve my example. Drawing the axis can be done with the same method used to draw the landscape, and drawing the title can be done with a bitmapfont, as usual. If you want to fill the grid with colors, either you draw a colored mesh between lines but that requires some knowledge of OpenGL, or you draw points to fill the empty space between lines but that will be horribly slow.
