The question really is what are you trying to show with the graph, and what do you plan to use the graph for? If it is estimating the size of disk space that you'll need at some point in the future, that's fine. If it's for entertainment value, that's fine too. But if it's to try to make some claims about (for example) kernel complexity, you'd do better to measure the size of various specific subsystems, such as mm, core kernel, a specific file system, etc. And even then, the statistics can be misleading since sometimes refactoring to reduce complexity or removing unneeded abstraction layers can end up reducing the size of the subsystem, but leave it in a more maintainable state. - Ted
