Bar Graph   Ð

A Bar graph plots a group of up to three data lists (converted

to bars) for comparison among one category. Bar graphs are

especially useful for comparing data lists (especially when

organized in categories) over a period of time.
The calculator adjusts all bars so that they fit within the

graphing screen. Therefore, the data list with the largest values

is scaled to fit the screen, and then all other bars are graphed

relative to it. Each element in 

 defines a category. You

can define up to seven categories with up to three data bars

per category.
