There seems to be a huge misunderstanding here, and I am not sure what it is, but what you need to do is run examples and experiment with variations until you have some inkling of what mpl is actually doing. Start with http://matplotlib.sourceforge.net/tutorial.html.
Please note that the ticks are simply labeled locations--they have no effect on what data are plotted. When you do ax.plot(ind*dt, y), absolutely *nothing* is lost; every value of y in your array is plotted. mpl is plotting (x,y) pairs--all of them--and labeling the axes accordingly. To see what is being plotted, you can use plot(x,y,'ro'), for example, to plot each point as a red circle. Experiment with this. Don't worry right now about avoiding the pylab interface; take advantage of its simplicity to get the most basic plotting concepts straightened out via quick experimentation. Use the gui zoom button to see how axis labeling works. Make your own simple examples; plot random points, plot sin waves.
