[Tex/LaTex] Removing x and y ticks in PGFplot

pgfplots

I'm trying to disable the ticks from showing on this diagram:
I've tried using x tick=empty as you can see, but it doesn't appear to change anything since I'm not actually plotting in the axis, only using it for easy construction. Any ideas?

\documentclass{article}
\usepackage{tikz}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}[scale=0.9]
\begin{axis}[xtick=\empty, ytick=\empty, minor tick num=0, scaled ticks=false, xticklabel=\empty,yticklabel=\empty,axis x line=bottom,axis y line=left,xlabel={Volume}, ylabel={Pressure}]
\end{axis}
\draw [very thick][-latex](160pt,20pt)..controls(100pt,25pt) and (60pt,45pt)..(42pt,58pt);
\draw [very thick][-latex] (40pt,60pt)--(40pt,126pt);
\draw [very thick][-latex] (40pt,130pt)..controls(60pt,90pt) and (100pt,70pt)..(157pt,60pt);
\draw [very thick][-latex] (160pt,60pt)--(160pt,23pt);
\filldraw(40pt,60pt)circle(2pt) (40pt,130pt)circle (2pt)(160pt,60pt)circle(2pt)(160pt,20pt)circle(2pt);
\draw (160pt,20pt) node [below right] {$1$};
\draw (40pt,60pt) node [below left] {$2$};
\draw (40pt,130pt) node [left] {$3$};
\draw (160pt,60pt) node [above right] {$4$};
\end{tikzpicture}
\end{document}

I think pgfplots is a little bit of an overkill since it is only two lines to be drawn. However you can simplify a little bit using the ticks=none option.

\documentclass{article}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}[scale=0.9]
\begin{axis}[ticks=none,axis x line=bottom,axis y line=left,xlabel={Volume}, ylabel={Pressure}]
\end{axis}
\draw [very thick][-latex](160pt,20pt)..controls(100pt,25pt) and (60pt,45pt)..(42pt,58pt);
\draw [very thick][-latex] (40pt,60pt)--(40pt,126pt);
\draw [very thick][-latex] (40pt,130pt)..controls(60pt,90pt) and (100pt,70pt)..(157pt,60pt);
\draw [very thick][-latex] (160pt,60pt)--(160pt,23pt);
\filldraw(40pt,60pt)circle(2pt) (40pt,130pt)circle (2pt)(160pt,60pt)circle(2pt)(160pt,20pt)circle(2pt);
\draw (160pt,20pt) node [below right] {$1$};
\draw (40pt,60pt) node [below left] {$2$};
\draw (40pt,130pt) node [left] {$3$};
\draw (160pt,60pt) node [above right] {$4$};
\end{tikzpicture}
\end{document}

[Tex/LaTex] plotting two time series with bounds

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

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

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}

        legend style={font=\tiny, legend pos=outer north east, draw=none, cells={anchor=west},fill=gray,fill opacity=0.4,text opacity =1}
        ]

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

    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{$p(x)=460-2x$};

        \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) {$153.33$};
