The bar chart provides information about the sales of a drug company in three specific regions over 4 years, from 2002.
Overall, Europe and America underwent downward trends in the percentage of the company’s total sales, while the opposite was true in the case of Asia after four years. It is also clear that Asia became the region generating the highest sales in the first year.
Regarding the amount of money earned by selling medicine in America and Europe, America was the largest market with 41% of total sales in 2002. The former witnessed a sharp decrease to just 27% in 2004 before recovering to 30% in the final year. In contrast, the latter increased slightly from 34% in 2002 to 38% in 2004, which was the highest figure recorded among three regions in this year. But this figure dropped to 30% after only 2 years, sharing the same point with America at the end of the surveyed period.
In terms of the remaining category, the sales in Asia stood at only 25% in the first year, which was much lower than the counterparts. However, this figure saw an uptick and surpassed Europe and America before reaching 40% in the final year, becoming the biggest figure.
