• The color associated with the selected digital pen's plot

• The line style and width associated with the selected digital pen's plot

• Whether or not a plot line should be displayed on the graph for the selected digital pen

• The data to be displayed in the pen legend (as follows):

• Description (of the digital tag whose data is being plotted)

• Value (of the digital tag whose data is being plotted)

• Minimum (the minimum value for this digital within the time period configured for the graph)

• Maximum (the maximum value for this digital within the time period configured for the graph)

• Average (the average value for this digital within the time period configured for the graph)

• Number of Starts (the number of times this digital went from "0" to "1" within the time period configured for the graph)

• On Time (the amount of time this digital has had a value of "1" within the time period configured for the graph)

• Low Scale Range (the low scale range for this digital)
