I believe the command is 

	set isosamples <expression>

You can do 

	show isosamples


to find the current setting. This works with parametric plots to give
a closer 'mesh' on the surface.

I was hoping someone more knowledgable would answer but. . .

The data file should consist of blocks of point triplets.  Each block
should be the same number of lines long, and each block should be separated
from the other blocks by a CR/LF.  Each block represents a line along the
surface in one direction.  If the blocks are all the same length, gnuplot
assumes a bunch of parallel lines (or something).

The hardest problem that I had when generating the dataset with a FORTRAN 
prograj was separating blocks with a CR/LF.  I finally had to use a statement
like this:
	write(999,'(a)') char(13)
where 13 is the ASCII code for a CR. 

You should also 'set data style lines'


Hope that helps. . .

I need to plot a 32nd degree polynomial and gnuplot doesn't seem to like any
form of the function. Is there a way to concatenate functions in a way that
gnuplot would like? I tried using the fortran notation for continuing on the
next line but that didn't work. Right now I'm making a plot file externally.
It would be much nicer just to have gnuplot do it for me. The ploynomial
looks like this:

 32    i    32-i
sum c x (1-x)
i=0  i

If there is a way to do this then that would lead to another problem.
I would like to have gnuplot read in the coefficients, c, from a file.
I suspect there's an easy solution to this.

Comment out the lines with IUCLC and ONOCR.  They should be part of your termios.h
but it appears that not all systems define these.  They are not really needed,
and probably should be removed from the new 3.3 version.

If you have termios.h you probably should use it.

Gnuplot is gnuish software in name only.  If this happens with all such
software, then maybe you should complain to your vendor.  (I am sorry
that this does not sound very helpful.)

I have never seen this problem before.  Have you tried ^R or ^L?  Either
of these should retype the current line.  Or is the line still not echoed?
The problem with Unix is the vast number of different versions available that
are so similar, yet are different in subtle ways.

Not having ever seen your system, I do not know what it will take,
(but if you figure it out I would like to hear about it).
Anybody have any suggestions?

First of all, thanks to the developers of gnuplot for a fine program.
I've been using it for labs and instruction in the senior undergraduate
climatology course that I teach.

I would like to use splot to contour and draw a surface of gridded
data read from a file. Is this possible?  All I can do so far is plot
the actual data points. Here is what I do:

set parametric
set surface
splot "test.data"

which plots the data points, but no surface connecting them.

when I "set contour" there is an error message: "Can not contour non
grid data!" even though the data is defined on a regular grid. I have
no difficulty with surface plots of functions. I'm using gnuplot 3.2
on unix DECstations.

From the online docs:

-----------------------------------------------------------------------
Isosamples
==========

   An isoline is a curve parametrized by one of the surface parameters
 while the other surface parameter is fixed. Isolines are a simple 
means to display a surface. By fixing the u parameter of surface 
s(u,v), the iso-u lines of the form c(v) = s(u0,v) are produced, and 
by fixing the v parameter, the iso-v lines of the form c(u) = s(u,v0) 
are produced.

   The isoline density of surfaces may be changed by the `set
isosamples`  command. By default, sampling is set to 10 isolines per u
or v axis.   A higher sampling rate will produce more accurate plots,
but will take  longer. This parameter has no effect on data file
plotting.

      Syntax:
              set isosamples <expression>
              show isosamples

It is patchlevel 0 that is buggy, not patchlevel 1 or 2.
The set size command is not supposed to change the text size - 
if it does then set size 1,0.25 looks AWFUL!
The documentation in patchlevel 1 and 2 is wrong - the set size
command does not scale text.

You should use:
set terminal postscript portrait monochrome "Helvetica-Bold" 8.64
set size 0.3,0.36

Well, as it turns out, I've been using gnuplot (a little) on the DECstation
on the DECstation network here at U.S.C..  Like you said, ~username is
not recognized, at least not by the Bourne (/bin/sh) shell.  However,
the C-shell DOES recognize it (probably /bin/csh).  To do what you've
described, try something like the following:

gnuplot> !csh -c 'cd ~username/whatever ; ls -l'

Hope this helps!

The tilde is a construct of the C shell (/bin/csh), and is not
recognized
by system calls requiring a pathname.  In some of our programs here at
NIH
we substitute the value of the env var HOME for the tilde, which would
permit   cd "~/whatever"  but not the above syntax.

The above should work if /bin/csh is your login shell; however, the !
operation spawns a new subshell, so that even if you do change
directories,
as soon as the subshell exits, you're back in the directory you were in
before.

Hi,

I have been using Gnuplot v2.0 all along and hope to install Gnuplot v3.2
soon on my Sun4. However, I have a query re. the display of confidence
intervals in plots. Can I display a small vertical line with small horizontal
tics at the ends of the vertical tics at each date point to represent
the confidence interval associated with that data point. Any help in
this regard will be greatly appreciated.

I wouldn't mind using v2.0 for the same.

Dear Gnuplot,
   Gnuplot is excellent and we find it very useful.   It runs well on our
IBM RS/6000 but on our MSDOS machines there is a slight problem.   When doing
a large contour plot it often runs out of memory.   I have compiled with Borland
C 3.0.   I understand gcc allows use of extended memory.  Is this correct?  Can
I compile gnuplot with gcc or is there a better way to solve the problem?  I 
have tried using various memory models and overlays with bcc.
   Thanks for all your efforts on gnuplot - it is much appreciated.
