Graphics, Figures & Tables ⇒ gnuplot & tikz

[ZeeRaX]

I got the full path there, because I am using portable version of TexMaker and portable version of TeXLive and gnuplot.

I've tryied

Code: Select all

pdfcslatex -shell-escape -synctex=1 -interaction=nonstopmode %.tex

but when I start to compile file - "couldn't start the command".

Personally I think that problem is in TexMaker or TexLive, it cannot see the gnuplot. However command gnuplot from microsoft console seems to run gnuplot correctly (from any path).

This might the probable cause. But unfortunately I can't advise any further. On my machine everything is fixed installed.

Yes, this might be the problem :-/ But every other function worked fine so far.

I noticed that there is sigma on y-axis and it shouldn't be there

I don't want to ask more, but since you have it properly working. Can you compile again with following code?

Code: Select all

\begin{tikzpicture}[scale=1.25]
    \colorlet{col1}{blue!70}
    \colorlet{col2}{blue!60}
    \colorlet{col3}{blue!50}
    \colorlet{col4}{blue!40}
   \draw [help lines] (-4.25,-1.25) grid (4.25,1.5);
   \draw [help lines,step=0.25cm] (-2.99,0) grid (2.99,0.99);

   \draw[->] (0,-1.25) -- (0,1.5) node [above]
    % {$\displaystyle
    %    \frac{1}{\sigma\sqrt{2\pi}}\exp\biggl(\frac{-x^2}{2\sigma^2}\biggr)
    % $};

   \begin{scope}[smooth,draw=gray!20,y=0.3989422804cm]
        \filldraw [fill=col3] plot[id=f1,domain=-3:-2] function {exp(-x*x/2)}
            -- (-2,0) -- (-3,0) -- cycle;
        \filldraw [fill=col2] plot[id=f2,domain=-2:-1] function {exp(-x*x/2)}

        \filldraw [fill=col1] plot[id=f3,domain=-1:0]  function {exp(-x*x/2)}
            -- (0,0)  -- (-1,0) -- cycle;
        \filldraw [fill=col1] plot[id=f4,domain=0:1] function {exp(-x*x/2)}
            -- (1,0)  --  (0,0) -- cycle;
        \filldraw [fill=col2] plot[id=f5,domain=1:2] function {exp(-x*x/2)}
            -- (2,0)  -- (1,0) -- cycle;
        \filldraw [fill=col3] plot[id=f6,domain=2:3] function {exp(-x*x/2)}
            -- (3,0)  -- (2,0) -- cycle;
        \draw[black] plot[id=f7,domain=-4.25:4.25,samples=100]
            function {exp(-x*x/2)};
   \end{scope}
       \draw[->] (-4.25,0) -- (4.25,0) node [right] {$x$};

    \foreach \pos/\label in {-3/$-3\sigma$,-2/$-2\sigma$,-1/$-\sigma$,
            1/$\sigma$,2/$2\sigma$,3/$3\sigma$}
        \draw (\pos,0) -- (\pos,-0.1) (\pos cm,-3ex) node
            [anchor=base,fill=white,inner sep=1pt]  {\label};

    \draw (-0.1,1) -- (.1,1) node [right,fill=white,inner sep=1pt] {};

    \foreach \pos/\percent/\height in {1/34/0.5,2/14/0.25,3/2/0.125,4/0.1/0.1}
    {
      \node[text=col\pos,anchor=base,yshift=2pt,xshift=-0.625cm,
        fill=white,inner sep=1pt] at (\pos,\height) {$\percent\%$};
      \node[text=col\pos,anchor=base,yshift=2pt,xshift=.625cm,
        fill=white,inner sep=1pt]  at (-\pos,\height) {$\percent\%$};
    }
\end{tikzpicture}

Hope \sigma won't be there this time.

I really have to thank you again. I didn't expect much when I registered to this forum, but you are doing fine job here! I appreciate your work very much.
