Y Achse bei Diagramm zentriert

Siemo · Beitrag von **Siemo** » Di 9. Feb 2016, 09:17

Hallo,

ich bin begeisterter User von diesem Forum, bist jetzt konnten alle meine Probleme von mir durch suchen gelöst werden.

Bei diesem muss ich mich anmelden und hoffe auf einen schnelle Lösung. In dem Manual "PGFPLOT" habe ich auch nicht gefunden oder übersehen.

Nun zum meinem Problem:

Bei meinem Diagramm, möchte ich gerne die Y-Achse in der Mitte des Diagramms ohne Beschriftung platzieren.

Minimalbeispiel:

\documentclass[12pt,a4paper,oneside,
			BCOR=5mm,
			%numbers=noenddot,
			]
			{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{graphicx}		%Bilder einfügen
\usepackage{xcolor}

\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\usepgfplotslibrary{fillbetween} 
\usetikzlibrary{intersections}


\begin{document}
\begin{figure}[htbp]
\centering
 \begin{tikzpicture}[scale=1]
  \begin{axis}[hide y axis,
               axis x line = bottom,
               ytick=\empty,
               x post scale = 2.25,
               y post scale = 1.25,
               xmin=-3.5,xmax=3.5,
               xtick={-3,-2,-1,0,1,2,3},
               xticklabels={$\mu-3\sigma$,$\mu-2\sigma$,$\mu-\sigma$,$\mu$,$\mu+\sigma$,$\mu+2\sigma$,$\mu+3\sigma$},
               ]
   \addplot+[samples = 50,
            domain = -3.5:3.5,
            black,
            no markers,
            name path=A,
            ]
            {1/sqrt(2*pi)*exp(-.5*x^2)};
  \end{axis}
 \end{tikzpicture}
 \caption{Allgemeine Normalverteilung}
\label{eq:gauss}
\end{figure}


\end{document}[\code]

Entferne hide y axis und ergänze

axis y line = middle,
enlarge y limits={.1,upper},

Also

\documentclass[12pt,a4paper,oneside, 
          BCOR=5mm, 
          %numbers=noenddot, 
          ] 
          {scrreprt} 
\usepackage[utf8]{inputenc} 
\usepackage[T1]{fontenc} 
\usepackage[ngerman]{babel} 

\usepackage{pgfplots} 
\pgfplotsset{compat=newest} 
\usepgfplotslibrary{fillbetween} 
\usetikzlibrary{intersections} 


\begin{document} 
\begin{figure}[htbp] 
\centering 
  \begin{tikzpicture}[scale=1] 
   \begin{axis}[axis y line = middle,
                enlarge y limits={.1,upper},
                axis x line = bottom, 
                ytick=\empty, 
                x post scale = 2.25, 
                y post scale = 1.25, 
                xmin=-3.5,xmax=3.5, 
                xtick={-3,-2,-1,0,1,2,3}, 
                xticklabels={$\mu-3\sigma$,$\mu-2\sigma$,$\mu-\sigma$,$\mu$,$\mu+\sigma$,$\mu+2\sigma$,$\mu+3\sigma$}, 
                ] 
    \addplot+[samples = 50, 
             domain = -3.5:3.5, 
             black, 
             no markers, 
             name path=A, 
             ] 
             {1/sqrt(2*pi)*exp(-.5*x^2)}; 
   \end{axis} 
  \end{tikzpicture}

\end{figure} 
\end{document}

Das Paket pgfplots lädt übrigens tikz, das wiederum graphicx und xcolor lädt.

Danke für die Hilfe.

Aber ich habe den Code gekürzt und färbe die Fläche unter der Kurve ein. Mit dem einfügen der y Achse, wird die Füllung unterdrückt, warum?

Hier ist der komplette Code des Diagramms.

Ich kann Dir jetzt nicht sagen, warum das passiert. Es scheint irgendetwas mit dem durch axis y line=middle gesetzten enlarge y limits=false zu tun zu haben. Wenn Du noch ymin=0 ergänzt, geht es wieder.

Oder Du verwendest die Sternvariante von axis y line, die nur die Position der Achse ändert und nimmst weitere Anpassungen selbst über Optionen vor.

Entschuldigung erstmal für meine Späte Antwort.

Ich bedanke mich für die beiden Versionen, die beide mit Texpad (OSX) Editor nicht funktionierten.

Ich musste bei /pgfplotsset combat=newest setzten.

Den Code habe ich folgender Maßen geändert, nur Kleinigkeiten.
