I've added the yellow highlights to point out my question: how to prevent these portions of the curves from being clipped/cropped? It is even more noticeable the thicker the line width.

Edit:

I updated all my TeX-related packages (this was in MiKTeX 2.9 with PDF-LaTeX output viewed in Acrobat). Here is a close up of the PDF to show that it is indeed there:

I am not getting the crop. Is there any thing missing? Have you tried with some other viewer? – Harish Kumar Nov 4 '13 at 0:28
Are you using standalone or some form of cliping? – Qrrbrbirlbel Nov 4 '13 at 0:36
Hmmm... Using MikTeX 2.9, PDF-LaTeXing and that is the output as viewed in Acrobat. I shall investigate further... – JohnD Nov 4 '13 at 0:47
@HarishKumar: The missing part is just the highlighted parts are noticeably thinner than they should be. It shows up for me in all my viewers. – JohnD Nov 4 '13 at 1:04
@Qrrbrbirlbel: No, I don't use either of those. – JohnD Nov 4 '13 at 1:05
