Why not use more intuitive sigmas?

I believe that if instead of using sigma square in the relationship 0.2, 1, 5 and 0.5, the graph displayed curves for sigma in the relationship 0.2, 1, 5 and 0.5, it would convey a better grasp of the shape of the curve and the invariance of the standard deviation with respect to the curve.--Gciriani (留言) 14:28, 30 April 2018 (UTC)

Color vision test

The chosen colors could come from a color vision test, please make sure to use colors that are easy to distinguish (also use contrasting brightness especially not just dim red/green). 78.124.136.51 07:11, 5 January 2023 (UTC)
