The XY Scatter From Mean - 3*StDev originally uses two hidden data points. To show the norm to Mean + 3*StDev x and d*n*step data values replace the original two hidde in steps of StDev/100 points. The secondary Y-axis remains hidden. x density d*n*step To align the normal curve with the histogram data, I chos -4.17 0 0.04 identical Y-axis scales.

(In the exam -3.71 0 0.05 and step = 5, so n*step = 85.)
