few remarks

[<mi...@ph...>]

I had a look to changes in gnuplot cvs code over last >month.
I'd to present few comments:

***

There are new features in gnuplot. It would be nice to keep the NEWS
file up-to-date (write new features and list new files added to demo).

Also, a section "What is new in gnuplot 4.1" should be added to gnuplot.doc
(containing a short form of news with links to docs).

***

File ChangeLog.0: I propose it contains the following text on the first
lines saying:

This is ChangeLog for period from 1998 until gnuplot 4.0 release in April
2004==============================================================================
***

Bug:
On x11 (well, I haven't look to other terminals), points in the points and
linepoints styles are "handicapped" -- look by a screen magnificator (xmag,
kmag) to points obtained by:

set size ratio 1
plot sin(x)/x w point pt 2

***

"help filledcurves" is not very well understandable.
I propose the following:

 The `filledcurves` style is only relevant to 2-d plotting. Three variants
 are possible. The first two take a function or two columns of input data
 file, and may be tuned by options (see below). The default is `closed`, which
 treats the curve itself as a closed polygon. The second variant is to fill the area
 between the curve and a given axis, a horizontal or a vertical line, or a
 point. The third variant requires three columns of input data file: the x
 coordinate and two corresponding y coordinates (two curves); then, the area between the
 two curves is filled.

 Syntax:
 	...

 where the option (the first two variants only) can be

 ...

 Example for the third variant:
 	plot 'data.dat' using 1:3:4 with filledcurves

 Note: ...

***

postscript terminal contains new option "level2". I propose to add (or
rather change to) option "level1" -- I guess it is more natural to restrict
to PS Level 1 printer by saying "set term post level1" rather than
"set term post nolevel2". (Also, it may become confusing whether
"PS Level 3" printer is "level2" or "nolevel2").

****

When "make tutorial" (under Linux): File $HOME/.gnuplot should not be read
-- it may contain an offending command which breaks the make process.

Could the particular pieces of tutorial/Makefile[.am?] contain something
like
	HOME=/dev/null gnuplot ...
?

****

gnuplot.doc contains an example for using new features "title and
xticlabels":
1.
  plot 'datafile' using 1:(f($2)/$4) title 2 with lines

  I guess that a more transparent example could be the same as few lines
  above:

  plot 'datafile' using 3:4 title 2 with lines

  (it is not clear what is f($2), and the result is obviously division, not
  remainder?)


2. In gnuplot.doc, I propose that "help xticlabels" go (reference) to the
  same entry as "help using xticlabels".

***


Currently I have only web access to internet, so I cannot do any change into
cvs. Thus I'd like to ask others to submit my proposed features, if
agreed. Thanks.
