Re: How do I change the y-axis on an Excel chart from numbers towords. This will plot everything as zero values, since they are all text. You can fake it using one of these approaches: http://peltiertech.com/Excel/Charts/Y_CategoryAxis.html. http://peltiertech.com/Excel/Charts/DotPlot.html. - Jon.
First you must keep in mind that all ears of corn have an even number of rows, never an odd number. All average ears have between 12 and 20 rows. Still, it's difficult to tell at a glance whether an ear has 14, 16, 18, or 20 rows.
1 To ensure even exposure and heating of each ear, arrange the ears in a triangle for three ears, or a square for four ears.  Make sure the ears are not touching each other. Do not pile them up or let them overlap, or you may end up with under-cooked corn.
