Once you reach the limits of the instruments (and run out of observable matter) there is nothing there to graph, and the graph ends. Now, we know it doesn't extend to infinity because …

Rotation of spiral galaxies is measured by spectroscopic observations of emission lines such as Hα, H i, and CO lines from disk objects, namely population I objects and interstellar gases.In these lines the velocity dispersion is negligibly small compared to rotational velocity, which implies that the … how to paint ivy vines
