Allen commented:>>The way I understand the graph is that it displays the
amount of C14 in some
coal samples as a percent of modern carbon (meaning C12) . So 2 samples
(as
indicated on the graph) had the C14/C12 ratio of 0.1 percent (0.1%). Or
1 C14
atoms per 1000 C12 atoms -- 1 C14 / 1000 C12. That seems pretty straight
forward to me.>>
Tufte (read his book) argues that data like this is best displayed in a
simple table. As a graph it is unnecessarily more complex than the data
deserves. The complexity, of course, makes it look "more scientific" to
the lay reader.
