Your code must be plotting them that way (original and one with a slight offset). We cannot determine what you are plotting with reespect to (or as a function of) the ‘Standard Deviation’, however it would make sense that you could be plotting . It could be worthwhile to check for that.

There is another possibility:

The plot might have been drawn once with wider line width, and then a second time with narrower line width and line color 'white'.

True.

We won’t know until we see her code and data.
