Answer the question.Andrew creates a bar graph to show the increase in his company's sales. He wants to show the milestones - years in which sales reached 10 million, 20 million, 30 million, 40 million, and 50 million dollars respectively. The data are shown in the table below: 
In the graph, Andrew draws 5 equally spaced bars of heights 1 in, 2 in, 3 in, 4 in, and 5 in respectively. The height of each bar corresponds to the amount of sales. He labels each bar with the corresponding year (1975, 1985, 1993, 1999, 2003 respectively). Why is the graph misleading?
