No.. I know what e is. Excel gave me E in a graph.

Are you referring to "E" in a number, as in 1.00E+09? That is a
convention for writing numbers in "scientific notation". The "E" means
"times ten to the power of". Thus, 1E+09 is 1 times 10 to the power 9,
i.e. 1,000,000,000. In a chart, you can usually change the number
format.
