This graph tries to correlate vaccines with aluminum in them to autism. Aluminum, which is a metal we use in our daily lives, does not cause autism. This graph doesn't label all of its lines, and shows no causation.
On the other hand, a good graph shows how vaccines have been aiding in the eradication of diseases such as polio and measles, as shown here.
Both graphs have consistent scales, showing accurate information. It shows where the vaccine first began, and how that affected the amount of people afflicted.
