### semilogzaxis

Is there any possibility to use a logarithmic z axis like you can do with
semilogxaxis/semilogyaxis for both the other axis.

Thanks

Holger

### Re: Problem with scatter scr

Dear Stephane,

It seems the buggy behavior in texlive-pictures is a bug which has been

I can reproduce your issue on pgfplots 1.2.2, starting with pgfplots
1.3, it is gone (the current stable is 1.4.1).

It might help to install a newer version in a local texmf directory on

### Re: Quiver plots ind pgfplots (unstable)

Dear Thomas,

thank you for your positive feedback! I'm glad to hear that you find
pgfplots useful.

Concerning your question: quiver plots are fully compatible with table
input; just use "\addplot[quiver={u=\thisrow{<colname>}}}" as source
expression for u,v and w. I have added a corresponding example to the
related manual section.

If you want something like "x index", consider using

graphics for the background graphics?

Best regards

### Re: semilogzaxis

Hello Holger,

yes, there is such a feature: add the option "zmode=log" after \begin{axis}:

\begin{tikzpicture}
\begin{axis}[
xmode=log,
zmode=log,
ymode=linear]
...

Best regards

### Re: using external library truncates plot

Hi Stefan,

I can confirm the behavior -- seems there are difficulties while
computing the correct bounding box for the superscript.

I have experimented a bit and found the work-around to enlarge the tick
scale label a little bit:

\begin{tikzpicture}
\begin{axis}[y tick scale label style={inner sep=1pt}]
\end{axis}
\end{tikzpicture}

I will take a note on my todo list. Perhaps this can be improved
automatically without changing such sizes.

Thanks for reporting the issue.

Best regards

Christian

### Tick line thickness at start and end of axes

Hello everyone,

I'm relatively new to the excellent pgfplots package, so apologise if

I prefer to produce plots with the ticks on the outside of the axes.
I can set this using the pgfplotsset option tick align=outside.
However, I have noticed that when tick marks coincide with either end
of the x- or y-axes, the line thickness of the tick is reduced. I
provide a simple example below to illustrate this. Note that although
the tick thickness is set to semithick, the ticks at either end of
the axes are thinner than their counterparts that lie part way along.
I am wondering if there is a way retain the correct tick thickness at
these end points?

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.3,
every axis/.append style={semithick},
every tick/.append style={semithick,color=black},
tick align=outside
}
\begin{document}
\thispagestyle{empty}
\begin{figure}[p]
\centering
\begin{tikzpicture}
\begin{axis}[xmin=0,
xmax=30,
ymin=0,

### Controlling the order of legend entries

Hello everyone,

As I understand it, the order of the legend entries should generally
match the order of the plots. I understand that I can reverse this
order by using the reverse legend=true or legend reversed=true
commands, but is it possible to control the order of the legend
entries independently of the order of the plots? Let's say for
example that the order of my plots is 1, 2, 3, 4, but I want to list
the corresponding legend entries in the order 3, 1, 4, 2. Is this
possible?

Any assistance would be very gratefully received.

Best regards,

### Re: pgfplotsset-error with a given example


I'm having the same problem. The reason was, indeed, an old version (1.2.2)
of the pgfplots.sty.

Now I did change that and it shows on the log-file, that TeXShop is using
version 1.4.1

Unfortunately there still remains the error-messaga: I do not know the key
'/pgfplots/compat' ...

any hints? Are there more packages to be updated and if so which?

hope you can help me - thanks

### Re: pgfplotsset-error with a given example

Hello Zippel,

if I am not mistaken, the error message can only occur due to an
incomplete / broken installation. Perhaps there are still files from
pgfplots 1.2.2 (which does not know the /pgfplots/compat key).

It could arise in case you just replaced the single file pgfplots.sty
which, in fact, contains hardly more than the version number, the
package file name and  include commands.

Are you sure that you installed the new version of pgfplots completely,
preferrably separate from the system-maintained package repositories?

If you are sure, then you may include a '\listfiles' command as first
file. This, along with the generated .log file, could help me to
identify problems.

Best regards

Christian

### Re: Tick line thickness at start and end of axes

Dear Robert,

what you report as sub-optimal has once been considered to be a feature:
that very thick tick lines are bounded by the axis rectangle in some
"proper" way.

Perhaps it was "too" proper...

Well, there is currently no option to disable the feature.

I admit that I am not quite sure if it is actually a bug or a feature,
so I won't fix it (immediately).

But I can propose a technical work-around which will do for your
application: using the preamble command

\makeatletter
\def\pgfplots <at> drawtickgridlines <at> INSTALLCLIP <at> onorientedsurf#1{}
\makeatother

will deactivate the special handling and all tick lines will have the
same dimensions -- just as requested.

Does this solve the issue? If you believe that I should incorporate such
a change (at least as option), then write again.

Best regards

Christian
