When the items being tallied are numbers, a line plot can be used to visually display numerical data. A line plot uses X marks above a number line to show the frequencies. 1234567 Number of Books Read XXXXXXXXXX XXXXXXXXXX XXXXXXXXXXXX X XXXXXXXX The X marks above the number line show the frequencies. The Number Line shows the number of books read.
