[Gnuplot-bugs] GNUPLOT: 'set timestamp' error - 2

[Victor J. S. <sla...@pa...>]

Hans,

      Thank you for your reply and explanation that
1) gnuplot 4.2 specifies that the keyword 'offset' should be included
    with the timestamp offset parameters, and that
2) I should use the version 4.2 manual with gnuplot 4.2 .
    I have now downloaded that manual from http://www.gnuplot.info/:
.        "gnuplot, An Interactive Plotting Program"
.        version 4.2, manual prepared by Dick Crawford
.        3 March 2007 .

      I have tried using the set command you suggest:

      set timestamp rotate offset  ,4                              (5)

This command fits the command syntax specified on page 128, sec. 43.67
"Timestamp" in the above referenced manual:

      set timestamp ... {rotate} {offset {<xoff>} {,<yoff>}}    .  (6)

BUG REPORT

      But when I use your command with the 'offset' keyword, I still
get the error message

.    set timestamp rotate offset  ,4
.                                 ^
."plotorb", line 4: invalid expression

just like before.  This occurs using
.                  GNUPLOT Version 4.2 patchlevel 0
.                  last modified March 2007
.                  System: Linux 2.6.20-1.2952.fc6
[Changing to 'set timestamp rotate offset 0,4' cures the problem.]

CONCLUSION

      The above reported timestamp error is either
a) a bug in gnuplot 4.2 or
b) a typo in the version 4.2 manual, p.128, sec. 43.67 "Timestamp".
    The syntax should read

      set timestamp ... {offset {<xoff>{,<yoff>}}}                 (7)

This syntax is slightly different from the syntax expression (6) above.

      Thank you for your help on this matter.  I am not subscribed to
the list.

As of 4.2, it will.  The syntax in version 4.2 uses keywords in several
places where implicit ordering of command line elements was used so far.
   The equivalent command according to the manual for version 4.2 would be:

	set timestamp rotate offset  ,4

It's actually neither, because you appear to be looking at an outdated
version of the manual.  The version 4.0 manual doesn't apply to version 4.2.
