This plots a time series of a statistic for certain countries. When the chart first appears, you will see lines for the two countries that have the highest and lowest values for the selected year, as well as the selected country (if there is one). Choose additional countries from the list at the left. The small gray crosses show the median value for all the countries, and the gray lines represent the values for the top and bottom quartiles for each year. This type of chart can help you identify and examine trends.
