Chapter 6: Statistical Plots 117 Pictograph Î In a Pictograph, an icon symbolizes the quantities being represented. Pictographs are useful for observing changes in quantity over time. They also can illustrate comparisons between similar situations. The calculator displays no more than seven Pictograph icons for up to seven categories on the screen. Therefore, if Scale is not big enough (meaning that Data List is broken up by more than seven icons), you get an INVALID DIM error. If an element in Data List is too large to fit the maximum scale (99999) so that the calculator can’t make all icons fit in one screen, you get a DOMAIN error. ³ For your geography class, you want to compare distances (in kilometers) between Dallas, Texas, and seven other cities in North America. Use a vertical Pictograph to display your results. City km Toronto, ON 2215 Mexico City, MX 1775 Los Angeles, CA 2180 Washington, DC 1927 City km Denver, CO 1397 Kansas City, KS 836 Vancouver, BC 3444 1. Create two lists in the List editor, CITY and DIST. Remember to surround the first categorical list element with quotation marks (found in the Text editor). 3 For more information on entering lists, see Chapter 5: Lists. Categorical list Numerical list
