Found this, the other day. In “Die Welt”. A national, daily German newspaper. It’s scaring its readers. With a dumb chart or, as they call it, “Chart of doom”. For stocks. Like in 1929.
A memorable parallel: Similarities before the great crash in 1929 and today are striking. Dow Jones in points. Source: welt.de, 2014–02–18.
“Die Welt” says there are similarities. Because it uses the wrong scale. But look at the axes. Left: 200 to 350 (+ 75 percent). Right: 13,000 to 16,000 (+23 percent). That’s mean. Or dumb. Or both.
This is how it looks with the right scale:

The chart below works, too. Both time series on top of each other. Both start with 100. That’s good, too. But you can’t see the values anymore.
