Scaling pgfplot axis with labels at end of axis

pgfplots

I have the following tikzpicture where the axis labels are anchored at the end of the axes. (code is at the bottom)

So far so good except that when I want to scale the axes (uncomment the line below), the labels goes off the supposed positions. In this example, it even fails when the x and y scales are set to the same value. (It works if I do scale=0.7 in this case, but in general different scale factors might also be needed for the two axes)

Any suggestion on how this can be fixed please?

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}


\pgfplotsset{
  compat=1.17,
    mystyle/.style={
        axis x line=middle,
        axis y line=middle,
        every axis x label/.style={at={(current axis.right of origin)},anchor=west},
        every axis y label/.style={at={(current axis.above origin)},anchor=south},
        every axis plot/.append style={mark = none, draw=black},
    },
}


\begin{document}

\begin{tikzpicture}
\begin{axis}[
       mystyle,
        xlabel=xlabel,
        ylabel=ylabel,
        % xscale=0.7, yscale=0.7  % uncomment this
  ]
  \addplot coordinates {(1,1) (2,-1)};
\end{axis}
\end{tikzpicture}




\end{document}

Best Answer

If you replace

every axis x label/.style={at={(current axis.right of origin)},anchor=west}

with

xlabel style={anchor=west},

then using xscale=0.7 works fine:

Notes:

Axis labels were modified to be in math mode.
Using ymax=1.1 eliminated the issue of the dot being on top of the arrow.

Code:

\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}

\pgfplotsset{
  compat=1.17,
    mystyle/.style={
        axis x line=middle,
        axis y line=middle,
        %every axis x label/.style={at={(current axis.right of origin)},anchor=west},
        xlabel style={anchor=west},% <----- Revision
        every axis y label/.style={at={(current axis.above origin)},anchor=south},
        every axis plot/.append style={mark = none, draw=black},
    },
}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
       mystyle,
        xlabel=$x$,% <----- Now in math mode
        ylabel=$y$,
        xscale=0.7, yscale=0.7,
        ymax=1.1,% <----- Added
  ]
  \addplot coordinates {(1,1) (2,-1)};
\end{axis}
\end{tikzpicture}
\end{document}

[Tex/LaTex] Preserving styles while changing axis y line in pgfplots

OK, I got somewhere - except the I cannot get the plots' combined width to fit within the margins (hope someone will offer a solution for that):

Otherwise:

Aligning the xlabel, ylabel: is a bit of a pain; note the manual states:

The starred versions . . . line* only affect the axis lines, without correcting the positions of axis labels, tick lines or other keys which are (possibly) affected by a changed axis line.

which in this case means that I should first set axis y line=middle to set the label position as I want it, then re-set with axis y line*=left afterwards, so only the axis position changes (this also adds the 0 as ytick label)

the zero to appear as first x axis tick label on the left-hand plot - similarly, by "overloading" with axis x line*=bottom
the zero to disappear as first y axis tick label on the right-hand plot - somewhat tricky, but seems that only thing that works, is "overloading" yticklabel and setting a conditional command via \ifnum in there, that uses \ticknum (which apparently starts from 1).
the axes tick label font - the problem is that by default, pgfplots typesets axes tick labels in math mode; as example - I've left the yticklabel overload so it typesets the number directly, and it can be seen it is in Times. Otherwise, Change font also on axes in pgfplots explains that an additional package has to be loaded to use Times as math font, and for me \usepackage{txfonts} works (though I bumped in the problem described in Local font installation problems, and the solution there worked for me).
auto xshift of scope: a similar problem is noted in pgfplots - Positioning a tikz scope relative to another tikz scope. This is not quite auto, but I use half of \textwidth minus half of intended separation to set the width of a plot; as it can be seen from the image, it's almost there but not quite right with the margins; will probably have to test the suggestion of @JohnKormylo, too

[Tex/LaTex] Location and size of pgf plot axis in a tikzpicture – with tikz positioning library

I do not know why that syntax doesn't work, but you can use the syntax of the calc library. While not exactly the same, it does allow you to place axes relative to other nodes/coordinates. Note that the default anchor for the axis is south west, change that if desirable.

In the code below I used at={($(nodeOne)+(0cm,1.5cm)$)}. When no anchor for the node is supplied (e.g. nodeOne.west), the center anchor is assumed. As you can see, the lower left corner (anchor=south west) of the axis is 1.5cm above the center of nodeOne.
