#2609 For "plot" command, the index feature can not be used with stringcolumns.

[Anonymous]

Gnuplot version 5.4 patchlevl 5, Windows
The index feature can not be used with stringcolumns.
For a datafile with two data sets, e.g. like this:

---

"comment" "comment"
"comment" "comment"
"comment" "comment"
"LabelX" "DataY"
"P1" 1
"P2" 2
"P3" 3

"comment" "comment"
"comment" "comment"
"comment" "comment"
"LabelX" "DataY"
"P1" 1.1
"P2" 2.2
"P3" 3.3

---

gnuplot> plot "FILE1" index 1 using "DataY":xticlabels(stringcolumn("LabelX")) skip 3 exit with linespoints
warning: no column with header "DataY"
^
all points y value undefined!

The command line had a typo (an extra word "exit")
It should be
gnuplot> plot "FILE1" index 1 using "DataY":xticlabels(stringcolumn("LabelX")) skip 3 with linespoints

[Karl Ratzsch]

Data sets are separated by two blank lines in the data file, and the first set has index number zero.

[Ethan Merritt]

Also "skip 3" is applied to the file as a whole, not to individual data blocks inside it.
