Hi Stephan,
gnuplot knows two different types of numbers, real and 
integer. See help expressions for more details. Your error 
occurs, when you use integers instead of real numbers. Try 
this:
print 10**-14
  3.61732686836958e-09
print 10**14.0
  1e-14

[Gnuplot-info] calculation/potentiation errors

[S <ste...@gm...>]

Hello,

I am trying to produce plots on very broad ranges of numbers (as broad
as between 1e20 and 1e-10). I have discovered, that when I try to
calculate e.g.
10**-14
the result is somewhere at 1e9. These miscalculations make my plots
incorrect.

Minmal command to reproduce the problem:
   print 10**-14
the result is
   3.61732686836958e-09
when it should return 1.0e-14 .

Is there a way to solve this or a workaround? Why is this so?

Thanks,

Stephan

[Gnuplot-info] pm3d versus image and rgbimage

[Rudolf I. <rud...@ya...>]

Dear Supporter,

I would like to plot a 2D histogram as a map. 

Until now, I have used the "pm3d map" plotting style to visualize my 2D histograms. But this is an interpolation not a real histogram, and it becomes especialy inconvenient when 
(i) the binsize must be large (eg. staying for originally discrete data), or
(ii) the histogram is sparse (a lot of counts in one region and nearly nothing in others). For sparse 2D histograms it seams inpossible to put zeros invisible without having lost individual counts in sparse regions.

I have recently found the new plotting style "image" in the documentation, and it seemed -  for the first look - to be exactly what I needed. But I realized that I cannot adjust the third (Z or color) axis's range. The only way to influence the color scale is to "set logscale zcb".

Then, I turned to the style "rgbimage". I have processed the histogram file to contain the desired colors. But now, there is no trace of the colorbox on the right of the plot as it was with the "image" style.

My question is: 
Is there any way to plot 2D histograms (as maps) 
(i) without any manipulation (interpolation),
(ii) with freely adjustable third (Z or color) axis,
(iii) with a colorbox representing the counts' values in a color-scale
at the same time?

I would be very grateful if You could help me.

Sincerely Yours,

Rudolf Izsak

That conclusion is likely premature.  Something probably happened, but

You'll have to explain more carefully what kind of parameter you were

You assume that you can use the same inline data set multiple times, 
like you can read a file multiple times.  Unfortunately, that's not the 
case.  Re-read "help datafile special-filenames" for the details.

But you can quite easily combine your three files into a single one, if 
you've collected some needful tools about your work place.  Using the 
usual Unix tools, e.g., it would be as simple as:

	plot '< paste file1 file2 file3'

For more complex, use 'join' instead of 'paste', or write yourself a 
little data processing script.  And it may be preferrable to do it once, 
instead of each time you need a fresh plot:

	! paste file1 file2 file2 > files_1_2_3

[Gnuplot-info] building histogram chart with multiple data files

[seb_kramm <seb...@ya...>]

Hello gnuplot user's,

I'm new here, sorry for what may be a silly question...

I was very happy to find that 4.2 had histograms charts added, however, I have a 
question about it's usage.

 From the demos, it seems that it can only build that type of chart with multicolumn 
data files. And what I have is several 2 columns data files, produced by an app, with 
a parameter setting that changes between them.

Example:

# File1 |# File 2 |# File 3 |
# x - y |# x - y  |# x - y  |
1  3.4  |1  3.6   |1  3.7   |
2  4.5  |2  2.3   |2  3.3   |
3  2.4  |3  1.1   |3  3.5   |
  ...       ...       ...

Is there a way I can build an bar chart (histogram) out of these files ?
Reconsidering the way the files are build isn't easy, as there's a lot of preliminary 
computing for each, I just can't switch easily from a setting to another.

If not, maybe that's an idea of futur feature ?
Thank you all,

Due to licence issues you have to compile your own gnuplot if you want

You could and probably should test such 'not-quite-installed' packages 
where 'make install' is only an intermediate step towards building an 
RPM or whatever, in a shell with a modified $PATH, or in a chroot 
environment.

Yes.  It should render modifying TERMLIBS completely pointless.

More to the point, TERMLIBS is eventually auto-generated from 
configure's findings.  I.e. unless you're out to do something spooky, 
there should be no need to change what configure put in there.  It's 
easier to work with configure than to fight it.

I don't really know --- I personally don't do wxWidgets.  You may want 
to re-route this issue to the developers' mailing list gnuplot-beta on 
this same server (but please subscribe first, or I'll have to manually 
approve each posting, which can take a while)

The problem with this is that I would pick up a pre-installed=20
gnuplot binary from /usr/local/bin/gnuplot.  I explain below
why it is not a problem to specify the install path when
running gnuplot.

I believe I can show more conclusive proof below.

I believe not.  Here is the reason - when gnuplot is built, the
configure script is run with "--prefix=3D$PREFIX".  The path specified =
with=20
$PREFIX will determine these things:

o Where the package will be installed with "make install"

o The path will be compiled into the gnuplot binary so that it will
look at this path in order to find these resources:

  $PREFIX/libexec/gnuplot/4.2/gnuplot_x11
  $PREFIX/share/gnuplot/4.2/gnuplot.gih

As a demonstration, I'll move aside these directories and display the
results.

cd /tmp/external.rross

rross@shona1:/tmp/external.rross> ls
bin  etc  include  info  lib  libexec  man  share
rross@shona1:/tmp/external.rross> mv libexec libexec.sav

gnuplot>=20


Notice above that the gnuplot binary requires that the supporting files =
be
under the "hardcoded" prefix directory, otherwise it will not find them.
This
is true regardless of where the binary is picked up from, so having it =
in a
PATH variable is not necessary.  If I mv the directories back to their
original
names, everything will work again.  You can try this for yourself if you =
are
unsure about it. =20

The point from all this is that the support files are tied to the =
gnuplot
binary, and there is no danger of other files being picked up by an
extraneous PATH variable setting.

Now, it is possible to override the gnuplot_x11, and gnuplot.gih files =
by
setting these environment variables:

GNUHELP
GNUPLOT_DRIVER_DIR

If one wants to relocate the gnuplot install area, these need to be set
in order to override the precompiled directory locations.  In fact, we
have written a short wrapper script which sets these variables, and then
invokes the gnuplot binary.  This is necessary when we deliver gnuplot
as part of a larger product.  We can't predict where the customer will
install the entire release, so it is necessary to make this relocation
ability available.

However, I am not using these variables when testing.

You may be right about that.  However, the present purpose is to
determine whether it will work at all.  So far it has not.  If we
can get it to work, further choices will be made.  If it does not
work, no further choices are possible.

Fair enough on that.  I see from "configure --help" that many other env
variables will influence the configure script, but TERMLIBS isn't =
mentioned.
TERMLIBS here was intended to influence the "make" process though.  I =

the pkg-config information should help with this? =20

There's a bit of a terminology clash here.  gnuplot has parametric, but 
that's not at all what you're trying to do here.

Circles with variable pointsize are possible in version 4.2, in at least 
some terminals.  See 'help plot with', then page down to 'pointsize

That's not expected to be any improvement over

	./gnuplot

As I said: it should be run without specifying a path, to get the 
version that's actually installed.  Just like this:

	gnuplot

This, unfortunately, is not conclusive proof the installation is correct 
-- the gnuplot_x11 found this way could still be from a different 
version of gnuplot, mainly if you used environment variables to override 
default installation locations before.

I doubt that to be a viable option, mainly for X11 and stuff built on 
top of it (including wxwidgets).  You don't want to statically link libX11.

Wrong way round, I'm afraid.  Getting it to work with dynamic linking 
has no particular relevance to getting to work with static linking.

That will not work as planned.  You have to use configure arguments to 
specify which libraries you want, possibly overriding the entire library 
search path. The configure script doesn't do anything with TERMLIBS, so 
the autoconf'ed results will usually not match TERMLIBS.

I did a "make install" after the build was completed.  I'll mention
that I've had no problems in the past running ./gnuplot, but I went
ahead and ran it from the full path:

/tmp/external.rross/bin/gnuplot     (This is the install area)

The results were the same as before.  Also, the other terminal types
seem to be OK.  At least, when I did this, it worked.

set terminal x11
plot x*x             (parabola displayed in an X window)
splot x*x+y*y        (3-dimensional surface is displayed in X window)

I have included these items below:

- The configure parameters that I used in the build
- The link line from the log
- The output from "ldd gnuplot"

A bit more information.  The system used to compile this was SLES9.  =
This is

because we want to build it on a least common denominator, and have it =
run
successfully on other systems, like SLES10, RHEL4, RHEL5, and others.  =
The
eventual intent is to link the gnuplot binary statically (with the =
exception
of a few things like libm, libc) and distribute it along with a product =
that
calls gnuplot.  You will see many of the libraries that I compiled and
linked
in the 'ldd gnuplot' list.  Eventually we want to produce ".a" files and =

statically link the whole thing.  But first, it needs to work!

Also, the compiler used was gcc 4.0.2.  The machine native compiler, gcc
3.3.3
is not being used.  That is why some of the libraries are in
/usr/local/lib64,
(gcc 4.0.2) vs. /usr/lib64 (native installed compiler)

This is the 64 bit version.  When this works, we will also do a build =
for 32
bit.

You don't have to --- these files, along with all the other demo files, 
are part of the gnuplot distribution.

This way of starting gnuplot indicates potential trouble.

Better try use "make install" then just run

	gnuplot

(without the "./" to start it from the current working directory).

	ldd gnuplot

should be worth a look, to check for possible installation problems of 
one of those lots of shared libraries you installed immediately before 
building gnuplot...
