DrawingGrid/Moving Object

Where can I get 2D code examples of drawing 2 grids on one form and putting text at the botton of the vertical lines (each line represents a mile). I also need to be able to rescale when the user right clicks on the form Scale 1 = 10 miles. Scale 2 = 20 miles and Scale 3 = 30 miles.

Would the maps have to be redrawn if I were plotting a moving object accross them or just the object as it moves?
