This line chart shows the information about number of neutrons, number of protons and type of decay. To begin with, we can see that there are several categories, which are α,β, fission, proton, neutron and stable nuclide and unknown.  According to the graph, the largest figure conies from the blue color, which is β-. It’s followed by the orange color, which is β+. Last but not the least, the smallest figure comes from the pink color, which means the neutron. In conclusion, it’s a very useful line chart.
