[Tex/LaTex] Pgfplot/tikzpicture: modify ticks and labels

labelspgfplotstikz-pgf

I would like to modify my tikzpicture:

1.) I added an extra tick at x=92, but this overlaps with the automatic tick x=100. How to solve this overlapping? Same problem for the second extra tick at x=153.3 (which is actually the fraction 460/3 – how to label fractions?).

2.) I used \filldraw to create circles at intersections points. How to create a relative node as a label, like \node[] at (200,150) {p = MC}?

3.) Furthermore it would be nice to add additional labels (MC, MR, p) to the lines in relative positions.

\documentclass[13pt,a4paper,headlines=6,headinclude=true]{scrartcl}
\usepackage{tikz,pgfplots}
\pgfplotsset{compat=1.12}

\begin{document}
\begin{tikzpicture}[scale=1.5]
  \begin{axis}[axis lines=middle,xmin=0,xmax=349,ymin=0,ymax=549,
    extra x ticks={92},
        extra y ticks={20, 153.3},
    xlabel=$\scriptstyle x$,
    ylabel=$\scriptstyle p$,
    tick label style={font=\tiny}, 
        legend style={font=\tiny, at={(1.2,0.8)},anchor=outer north east, draw=none, cells={anchor=west},fill=gray,fill opacity=0.4,text opacity =1}
        ]
        \addplot[no marks,red,domain=0:250,samples=250, thick] {x};
        \addlegendentry{$MC(x)=x$};
        \addplot+[no marks,orange,domain=0:230,samples=150, thick] {460-2*(x)};
        \addlegendentry{$p(x)=460-2x$};
        \addplot+[no marks,yellow,domain=0:230,samples=150, thick] {460-4*(x)};
        \addlegendentry{$MR(x)=460-4x$};
        \path[draw=gray] (0,460/3) -- (460/3,460/3); 
        \path[draw=gray] (460/3,0) -- (460/3,460/3); 
        \path[draw=gray, dashed, thick] (92,0) -- (92,276); 
        \path[draw=gray, dashed, thick] (0,276) -- (92,276); 
        \filldraw (92,276) circle (1pt);
        \filldraw (460/3,460/3) circle (1pt);
  \end{axis}
\end{tikzpicture}

\end{document}

Thank you 🙂

They are lot of questions and I did lot of modifications, hence there is no point in giving the list of modifications made. Please study the code:

\documentclass[13pt,a4paper,headlines=6,headinclude=true]{scrartcl}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\usetikzlibrary{intersections}
\begin{document}
\begin{tikzpicture}[scale=1.5]
  \begin{axis}[axis lines=middle,xmin=0,xmax=349,ymin=0,ymax=549,
    extra x ticks={92,153.3},
    extra x tick labels={$92\rightarrow$,$153.3\rightarrow$},
    extra y ticks={20, 153.3},

        ]
        \addplot[no marks,red,domain=0:250,samples=250, thick,name path=red] {x}node[pos=0.95,below,text=black,font=\tiny]{$MC$};

        \filldraw (92,276) circle (1pt)node[right,font=\tiny] {label H};
        \filldraw (aa) circle (1pt)node[right,font=\tiny,yshift=-1pt] {label G};
        \filldraw (bb) circle (1pt)node[right,font=\tiny,yshift=-1pt] {label I};
  \end{axis}
\end{tikzpicture}

Here is another option where you put the extra x tick labels yourself.

\documentclass[13pt,a4paper,headlines=6,headinclude=true]{scrartcl}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\usetikzlibrary{intersections}

\begin{tikzpicture}[scale=1.5]
  \begin{axis}[clip=false,axis lines=middle,xmin=0,xmax=349,ymin=0,ymax=549,
    %extra x ticks={92,153.3},
%    extra x tick labels={$92\rightarrow$,$153.3\rightarrow$},
    extra y ticks={20, 153.3},
    %extra x tick style={ticklabel style={rotate=35,yshift=2pt,anchor=east,inner xsep=2pt}},
    xlabel=$\scriptstyle x$,
    ylabel=$\scriptstyle p$,
    tick label style={font=\tiny},
        legend style={font=\tiny, legend pos=outer north east, draw=none, cells={anchor=west},fill=gray,fill opacity=0.4,text opacity =1}
        ]
        \addplot[no marks,red,domain=0:250,samples=250, thick,name path=red] {x}node[pos=0.95,below,text=black,font=\tiny]{$MC$};
        \addlegendentry{$MC(x)=x$};
        \addplot+[no marks,orange,domain=0:230,samples=150, thick,name path=orange] {460-2*(x)}node[pos=0.95,above,xshift=3pt,text=black,font=\tiny]{$MR$};
        \addlegendentry{$p(x)=460-2x$};
        \addplot+[no marks,yellow,domain=0:120,samples=150, thick,name path=yellow] {460-4*(x)}node[pos=0.95,above,xshift=3pt,text=black,font=\tiny]{$p$};
        \addlegendentry{$MR(x)=460-4x$};
        \path[draw=gray] (0,460/3) -- (460/3,460/3);
        \path[draw=gray] (460/3,0) -- (460/3,460/3);
        \path[draw=gray, dashed, thick] (92,0) -- (92,276);
        \path[draw=gray, dashed, thick] (0,276) -- (92,276);
        \path[name intersections={of= orange and red, by=aa}];
        \path[name intersections={of= yellow and red, by=bb}];
        \filldraw (92,276) circle (1pt)node[right,font=\tiny] {label H};
        \filldraw (aa) circle (1pt)node[right,font=\tiny,yshift=-1pt] {label G};
        \filldraw (bb) circle (1pt)node[right,font=\tiny,yshift=-1pt] {label I};

        \node[font=\tiny,inner sep=1pt,] (92) at (80,-50) {$92$};
        \draw[-stealth]  (92) -- ++(0,2) -- (92,0);
        \node[font=\tiny,inner sep=1pt,] (153) at (170,-50) {$153.33$};
        \draw[-stealth]  (153) -- ++(0,2) -- (153.33,0);
  \end{axis}
\end{tikzpicture}

Simply use

\foreach \x in {5,10,...,80} %% <-- change here
             \draw (\x,1pt) -- (\x,-3pt) 
                node[anchor=north] {\footnotesize\x};

Or better option will be pgfplots.

[Tex/LaTex] pgfplot contour plot with both x-axes and y-axes ticks labels

Pgfplots has builtin support for one axis which receives tick labels. If you want tick labels on both sides of an axis, you can either post a feature request at sourceforge and wait for its resolution or generate a second axis for the opposite site.

Here is a solution for the approach with a second axis:

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat = 1.7}

\begin{document}

\begin{tikzpicture}

    \pgfplotsset{
        set layers,% --- CF
        , x tick label style={
             /pgf/number format/.cd,
             fixed,
             fixed zerofill,
             precision=1,
             /tikz/.cd
            }
          , y tick label style={
             /pgf/number format/.cd,
             fixed,
             fixed zerofill,
             precision=1,
             /tikz/.cd
            },
    }

    \begin{axis}[
        %   title = {$x \exp(-x^2-y^2)$}
        , xlabel = $x$
            , ylabel = $y$
            , domain = -1:1
            , y domain = -1:1
        , enlargelimits
        , view = {0}{90}
        , extra description/.code={% --- CF
                \xdef\XMIN{\pgfkeysvalueof{/pgfplots/xmin}}
                \xdef\XMAX{\pgfkeysvalueof{/pgfplots/xmax}}
                \xdef\YMIN{\pgfkeysvalueof{/pgfplots/ymin}}
                \xdef\YMAX{\pgfkeysvalueof{/pgfplots/ymax}}
        },
        ]

       \addplot3[
            contour gnuplot={
                  number = 10
                 },
             thick
            ]
         {
            776.062 -50.812* x + 153.062 * y -76.812 *x *y
            };

    \end{axis}

    \begin{axis}[% --- CF
        xmin=\XMIN,
        xmax=\XMAX,
        ymin=\YMIN,
        ymax=\YMAX,
        ticklabel pos=right,
    ]
    \end{axis}

\end{tikzpicture}

\end{document}

As you see, I extracted common options using a \pgfplotsset and wrote two axis environments. In addition, I automatically remembered the axis limits of the first axis and replicated them in the second. Note that the set layers statement synchronizes the layers of the two axes which is convenient especially if you plan to add grid lines. The solution currently draws the axis paths twice (except for the labels). That could be improved by means of axis lines statements.

Concerning your question about "trimming": could you add more details on what you mean here?
