Which Chart Doesn’t Fit With the Others?

Which of these 5 charts doesn’t fit with the others?…

 

  • Bloomberg Economic US Surprise Index

  • ¬†Yardeni Global Growth Barometer & S&P 500

Global_Growth

 

  • Monthly Core Retail Sales

Retail_Sales

 

  • S&P 500

SPX_Weekly

 

  • US Inflation Rate

What do you guys think? I would have to say the 4th chart looks quite different from the others, however, it looks oddly similar to the following chart:
