摘要：

Bar graphs are convenient for showing comparisons among items．The bars may be either horizontal or vertical,and they are used to show the amounts of different items．Figure 1 is an example of a typical bar graph．The graph shows the average sales price of existing homes in the Northeast United States for three years——1970,1980,and 1997．
