Description of problem:
The current version of gnuplot with Fedora Core 4 supports drawing vectors on in 2D. It can not draw vectors using splot.
According to http://cvs.sourceforge.net/viewcvs.py/gnuplot/gnuplot/NEWS?rev=1.98 that functionallity seems to be in gnuplot CVS.
I would very much like that to be patched into gnuplot for Fedora Core.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. try to use vectors with splot
2. gnuplot> splot [-2:2] [-2:2] [-2:2] '-' with vectors
3. input data ('e' ends) > -1 -1 -1 1 1 1
Actual Results: it plots a point, rejects the 5th and 6th data points needed
Expected Results: should draw a vector from (-1,-1,-1) to (0,0,0)
Works fine with 2D
gnuplot> plot [-2:2] [-2:2] '-' with vectors
input data ('e' ends) > -1 -1 1 1
input data ('e' ends) > e
results in a vector from (-1,-1) to (0,0)
but vectors are not implemented for splot
I built todays CVS based on core 4 spec file - buffer overflow in x11 terminal,
png terminal not available, pslatex terminal works - but the last 3 lines of
resultulting tex file are missing and have to be manually added - but then the
splot vectors works very well.
I don't know their release schedule for 4.2 but it *would be nice* to at least
have the splot vectors (if possible) backported into 4.0.0 for fc5 - if possible.
I'll probably just build the 4.1 cvs in an odd install location and use it just
for pslatex (what I need anyway) with splot vectors, so my issue has workaround,
but *would be nice* rfe for FC5.
I'll keep track of the updates for the official gnuplot. I'd rather not update
to a CVS version for all users though as the stability as you've seen sometimes
is rather flaky for those.
And backporting doesn't really make much sense if a new version is supposed to
come out in a reasonable timeframe.
Read ya, Phil
This bug is fixed in upstream cvs.
