This bug is fixed in Version 1.2.6.

The behavior was indeed erroneous; there was an overly-enthusiastic validity test in triples.cc, which incorrectly flagged points having coordinates larger than about sqrt(10^5). The patch file triples.cc.patch should fix the problem.

Hi,

I'm new to epix so this may be user error, but it does seem more likely to be a bug.

I am trying to draw a Maxwell-Boltzman speed distribution (in this case using the angular speed of apparatus which relates to velocity) and the plot stops after a small proportion of the line is drawn. If I use the riemann_sum instead then I get a complete picture. It seems as if the eepic file is not being properly created in the first case.

I have tried with the version 1.24 from a debian repositary, and 1.25 compiled from source with the same result. I'm using latex to create a dvi.

The Maxwell.xp program has the plot lines active and riemann_summ commented out for ease of testing.
