Description: This graph plots the last 10 years of highest recorded temperatures in Northampton, MA, USA. Important customizations include the labeling of angular axes with months and manipulation of symbol plot color by increasing color intensity from 2003 to 2012 (2003 is light magenta, 2012 is red).
The line+symbol plot for 2013 data is added to the plot after it is created, using the Add Plot to Layer menu command.
