The given bar chart illustrates the proportion of the entire revenues of a pharmaceutical business, by area, over a period of 4 years, starting from 2002.
Overall, there was a downward trend in the share of a drug business’s total incomes in America and Europe, whereas an opposite trend can be seen in the figure of Asia. Notably, the total earnings of a medicine company in Asia were lowest at the start of the period but ranked first in the last year.
In the first year, the data of America began at 41%, and in the next 2 years this figure dropped significantly to 27% before recovering slightly by 2% at the end of the period. Likewise, in 2002, 25% was the rate of the whole profits of a pharmacy business in Asia, after which it experienced a considerable upward trajectory to surpass America in 2004. Another notable point is that this data still kept its trend to rank first in the final year.
Looking at the chart, the percentage of a drug enterprise’s general sales in Europe accounted for 34% in 2002, after that this figure witnessed insignificant growth in the next year. Another notable point is that its figure reached a peak of 38% in 2004, followed by a considerable fall to bottom out at 30% in 2006.
