Using JMP 15, the Analyze->Distribution density curve is not fitting properly. A few examples below. The parameters for the fitted normal seems correct, but the density curve is off. Works fine for "life distribution" density curve or when i multiply the data by eg. 1000. What's going on here?

Fitted Normal Distribution

Parameter		Estimate	Std Error	Lower 95%	Upper 95%
Location	μ	0,0143429	0,0002075	0,0139362	0,0147495
Dispersion	σ	0,0007763	0,0055724	6,025e-10	0,0008905

Parameter		Estimate	Std Error	Lower 95%	Upper 95%

Dispersion	σ	0,0011681	0,0068354	1,22e-8	0,0013398

This appears to have been an issue in Version 15. When I used Version 17(currently shipping version) with your data I get the following:

I suggest upgrading.
