Hello,

I am pleased to announce the release of pgfplots 1.0, a high-level tool to generate line, scatter and bar plots based on the pgf/tikz plot handlers.

Interested users are invited to browse the documentation at

Congratulations.  I just tried pgfplots again, and it improved a lot since the
beginning of this year! :-)  Also, AFAICS the manual has improved a lot, and
there are many nice examples now.

Just a question: I tried

\begin{axis}[every linear axis/.style=->]
...
\end{axis}

which did not work, but this did:

\pgfplotsset{every linear axis/.style=->}
\begin{axis}[
...
\end{axis}

Is this intended?

I think I now understand my error, but did not find a way to fix it.  "every
[linear] axis" refers to the axis environment, so I probably have to define
the style beforehand (or include it in the options list).  The above
compiles, but adds arrow tips to all plots and ticks, too.

What I *meant* to do was affecting the axis *lines* only.  Maybe I don't see
the wood for the trees, but there only seem to be styles for the whole axis
environment, the plots, and the ticks?!

Great! I am particularly happy to see the ConTeXt support.
However, I set out right away to produce a real plot and immediately ran into
the following problem:
! Dimension too large.

Seems to be a problem handling semilog[xy]axis
\usemodule[pgfplots]
\starttext
\starttikzpicture
        \startsemilogyaxis[height=6.08cm,width=8.6cm,
                xmin=0,xmax=7,ymin=1e-2,ymax=2]
        \stopsemilogyaxis
\stoptikzpicture
\stoptext

Whereas the following works under pdflatex:
\documentclass[a4paper]{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
        \begin{semilogyaxis}[height=6.08cm,width=8.6cm,
                xmin=0,xmax=7,ymin=1e-9,ymax=2]
        \end{semilogyaxis}
\end{tikzpicture}
\end{document}

Has anyone tried using pgfplots under ConTeXt?

Hello Alan,

you are right, ConTeXt support is not readily tested. In fact, I only tested two logarithmic line plots (which did not cause any problems). Unfortunately, linear plots fail as you showed.

The CVS version of pgfplots is improved with respect to ConTeXt, and it is better tested. The reported bug does no longer occur.

Hallo Hans,

I guess you found a missing feature, namely a style which affects only the axis lines. I will add such a style to the CVS these days.

Concerning the 'every linear axis' style, I will check whether I can improve the evaluation inside of
\begin{axis}[...]
Maybe I simple got something wrong.


Regards,

Christian

That would be nice.

Also, please consider automatic disabling of enlargelimits when axis lines are
not drawn as a box as a feature request. :-)

I don't think this is necessary.  After all, inside \begin{axis}[...], one can
simply put the options directly (or define the style beforehand).  I simply
thought "every linear axis" was the above missing style, in which case the
scope would have been smaller than the axis environment.

Thanks for your \pgfpointanchor-suggestion, too.

It looks great. I have tried to install it with miktex package manager
but I get an error. Is this a bug in miktex packaging or in the package?

After some advice from Christian I found that what I needed was an
update of Miktex before installing pgfplots.

Hello,

I seem to have stumbled upon an obscure bug in pgfplots (1.1)
using ConTeXt  (ver: 2008.05.21 15:21 MKII).
A (close to) minimal example is:

%\enableregime[utf]
\usemodule[pgfplots]
\starttext

\starttikzpicture
        \startaxis[xmode=log,ymode=normal,xlabel=$T$ (K),ylabel=$dV/dT$ ($\mu$V/K)]
                \addplot[blue,mark=none] table[x index=0,y index=2] {thermocoupleE.dat};
                \addlegendentry{Chromel-Constantan (type E)}
        \stoploglogaxis
\stoptikzpicture

\stoptext

which compiles fine. However, uncommenting
\enableregime[utf]
yields a compile error, as the data file contains a utf8
extended character (\mu).

A work-around for the time being is to avoid extended
characters in the data file column headers...

Thanks.

Alan
