The bar charts provide information about the proportion of food and goods purchased from supermarkets in three European countries from 1998 to 2008.
Overall, there was an upward trend in supermarket sales across all countries, regardless of the type of products. It is also clear that country B accounted for the highest percentage of food and goods bought from supermarkets in 2998, but it had been overtaken by country A in 2008.
In terms of food sales, all witnessed an upward trend after ten years, with the most significant change being recorded in nation A, where the percentage of food bought in supermarkets rose to 35%, moving it from the second position to the first position. Meanwhile, country B and C increased slightly from about 24% and 7% to approximately 27% and 9%, respectively.

However, by 2008, country A experienced a remarkable increase, reaching almost 40%, surpassing the slower growth in country B to above 27%. While country C consistently had the lowest figures, growing from over 2% in 1998 to almost 15% in 2008.
