Update of bug #53832 (project octave):
Status: None => Duplicate
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #1:
Alas, this is just another manifestation of the fact that OpenGL uses single
precision variables for plotting while gnuplot, and Octave, use doubles. See
bug #32980 from 2011.
The solution is to scale the data before plotting. In this case, the
timestamp has a large constant value of 736177 and then a small changing value
of order 1. I just subtracted off the first timestamp value which then
reveals that the range of data is [0, 2.17]. I have attached that as
bg2.dat.
If you modify plotbug.m to load bg2.dat you will see that the plot is
correct.
Marking as a duplicate and closing report.
