1950-1985 and 1985-now are pretty steady. Decreased inflation volatility over time.
I think your chart shows the "that inflation slowly erodes purchasing power over time." That doesn't mean there aren't periods of change - if you study economic history at all you know about the Great Depression and stagflation - but for ~50 years it's been pretty well managed.
