To reveal the difference in the application code, each panel is further split into two horizontal frames, with the upper frame showing the online store and the lower part showing snippets of the code.

为显示应用程序代码的差异，每个面板进一步分为两个水平框架，上面的框架显示在线商店，下面部分显示代码段。

Over that same period of study, the difference between the best- and worst-performing sector was over 200%, so the year-to-year difference between sector performances is magnified over longer time frames.
