Gnuplot 3.8i and 4.0 both crash while plotting a data file using a
format specifier on a data file. The data file has 21 comma separated
columns where every third column is a text formated date (which I
ignore):
#101(Time stamp),101(Seconds),101(C),102(Time stamp),102(Seconds),102(C),103(Time stamp),103(Seconds),103(C),104(Time stamp),104(Seconds),104(C),105(Time stamp),105(Seconds),105(C),106(Time stamp),106(Seconds),106(C),107(Time stamp),107(Seconds),107(C)
"2003-09-10 12:14:43.748",0.019,+2.448500E+01,"2003-09-10 12:14:43.968",0.239,+1.652400E+01,"2003-09-10 12:14:44.178",0.449,+1.645500E+01,"2003-09-10 12:14:44.387",0.658,+1.638900E+01,"2003-09-10 12:14:44.597",0.868,+1.633000E+01,"2003-09-10 12:14:44.807",1.078,+1.624000E+01,"2003-09-10 12:14:45.616",1.887,+1.617400E+01

a minimum sample which still works:
------------------------
reset
set nologscale y
set xrange [-20:20]
set autoscale y
plot \
'030910alogg.csv' \
every 1:::0::0 \
using ($1<4700? $1/60.0-60.0:1/0):($2) '"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf'\
axes x1y1 \
title 'center temp.' \
with lines linewidth 4 \
;
------------------------
but adding another column to the format specifier crashes Gnuplot on
Win32 (WinXP sp1+updates):
------------------------
reset
set nologscale y
set xrange [-20:20]
set autoscale y
plot \
'030910alogg.csv' \
every 1:::0::0 \
using ($1<4700? $1/60.0-60.0:1/0):($2) '"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf,"%*[^"]",%lf,%lf'\
axes x1y1 \
title 'center temp.' \
with lines linewidth 4 \
;
------------------------
...independently on which pair of columns I select to read.
Earlier I was able to plot this same datafile with GnuPlot 3.7x where
the column separator could be redefined to be a comma instead of a
whitespace...
Any ideas?
Uwe.

None of gnuplot's plot styles uses more than 7 'using' specifiers, so the format string isn't expected to contain more than 7 instances of %lf. You should replace the %lf for those columns you aren't going to actually use by %*lf, which parses a number but then ignores it. So the real bugs are two-fold: this limitation should be documented in 'help using', and exceeding the limit should yield an error message rather than crash gnuplot. I'll see how this can be fixed. > Earlier I was able to plot this same datafile with GnuPlot 3.7x where > the column separator could be redefined to be a comma instead of a > whitespace... You're mixing up versions here, I think. I'm quite positive none of the officially released 3.7x versions had such an option; i.e. yours must have been a modified one. gnuplot 4.0, OTOH, does have this option. See "help separator". -- Hans-Bernhard Broeker (br...@ph...) Even if all the snow were burnt, ashes would remain. |

Hi Hans-Bernhard, thanks for this incredibly fast reply! Yes I mixed up versions, partly because set datafile separator is not listed in the help, nor in the list of options when you write set on a Gnuplot 4 command line either... See my second message a minute ago, I solved the problem by using the datafile separator again... Uwe.

I guess this is caused by the gnuplot.doc not containing these nodes in alphabetically sorted order, or by some slight mistake in the structure of node header lines in gnuplot.doc, the file all the various editions of the documentation are generated from. I don't fully understand how the Index of the .hlp is generated from the RTF file, which in turn is generated from gnuplot.doc, so it's hard to see what's wrong there. -- Hans-Bernhard Broeker (br...@ph...)

It's also available just as "separator". In other words, you tried exactly those two out of four possible keywords it might have been indexed under, where it's not. ;-) [And, for the records, gnuplot-bugs@ is not *my* personal mail address, so it kind of misses the point putting my name on it...] -- Hans-Bernhard Broeker (br...@ph...)

Hi Hans-Bernhard, you are right, right and right. Sorry for taking up your time and bandwidth with something which mainly was a common user error... Still, "set datafile separator" is _not_ listed among the functions you get when you simply type "set" on the GnuPlot 4 command line, which was the first thing I tried, long before looking into the documentation. Your name got added to the address line by my email program (TheBat!) by default. Uwe.

I might have been a bit confuse concerning the
set datafile separator ","
since it is not mentioned in the index of the Gnuplot 4.0 help file.
The example given below works fine now again without giving the format
specifier in the using directive but by switching to comma as
separator character.
It appears that my newsreader treated the data file lines badly, so I
attach a sample data file...
