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 

 is

not big enough (meaning that 

 is broken up by more

than seven icons), you get an 

 

 error.

If an element in 

 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 

 error.

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.
