This is an example of a graph on which you could plot the dose-response curve for a chemical. The vertical y-axis extends from 0 to 10 and indicates the response of the seeds to the chemical. In this case, the response is the number of seeds that did not germinate. The x-axis gives the dose (as a percent concentration) and is marked at 0, 6.25, 12.5, 25, 50, and 100.
