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.
Corn will display signs of ripeness when it is ready for picking. Sweet corn (Zea mays) grows in U.S. Department of Agriculture plant hardiness zones 4 to 8. On average, it takes 60 to 100 days to ripen, depending on the variety. Knowing the maturity date will increase the chances of plucking ears of corn with the best possible flavor.
