Hi Samuel,
Fyi, adding a small number (~1e-6) to the last sample of the series results
in a good filled curve plot2d.
Le voilà:

Hi Samuel,
Thanks for pointing to the bug tracker.
I have read the explanations but could not find a workaround.
I hope what I say is mathematically correct:
The two data series provided in my example below seem to be topologically
equivalent and if true,
Yes, both are self-intersecting polygons. The limitation of the algorithm
does not say that none of self-intersecting polygons can be processed
conveniently, but that there is no garanty for some of them.
.../...
I.e., how to fix top data series provided so that it displays properly like
the bottom one?
By fixing the algo rewritten for Scilab 5.3.0 with heavy downgrades listed
in the comment w.r.t. the former one.
This is also showing in 3D and reported here:

Hello,
The attached simple Scilab script and data plots quite similar data as
filled curves in Scilab 5.5 (Win 7) with quite different results:
This is a known bug reported 2 years ago in
http://bugzilla.scilab.org/show_bug.cgi?id=11632
Any ideas of what can be causing the completely different behaviour of
plot2d / polyline_style = 5?
Please see comments #2 and #3 of the report.
Regards
Samuel
