### Normal Distribution on Error Bars  Topic is solved

This is a bit tough. I tried to draw normal distribution on every error bar. Since in this case the normal distribution has to be inverted. For example 1st normal distribution will be having mean 35 and standard deviation of 7.5. I tried to search so many things but every time they draw y as function of x. I am trying this for two days but could not find it.

\documentclass{article}\usepackage{pgfplots} \begin{document}   \begin{figure}[!htb]     \centering     \begin{tikzpicture}[scale=1],       \begin{axis}[         height=8cm,         width=14cm,           xmin=0,         xmax=4.5,         ymax=45,         ymin=20,         ylabel={Elastic Modulus E (Gpa)},         axis x line*=bottom,         axis y line*=left,         xticklabels={1,2,3,4},xtick={1,...,4},         x tick label style={anchor=east}       ]         \addplot+[black,only marks][error bars/.cd,y dir=both, y explicit] coordinates {           (4,32.32) +- (0,7.52)            (3,32.73) +- (0.0,8.0)           (2,33.24) +- (0,8.38)           (1,35) +- (0,7.5)         };         \node at (axis cs:4,32.32) [pin={120:(32.32,7.52)},inner sep=0pt] {};         \node at (axis cs:3,32.73) [pin={130:(32.73,8.0)},inner sep=0pt] {};         \node at (axis cs:2,33.24) [pin={130:(33.24,8.38)},inner sep=0pt] {};         \node at (axis cs:1,35) [pin={130:(35,7.5)},inner sep=0pt] {};         \addplot[color=black] coordinates {(1,35) (2,33.24) (3,32.73) (4,32.32)};       \end{axis}     \end{tikzpicture}%     \caption{Plot showing update for elastic modulus after each data step with trust factor}     \label{fig:bayesianupdatingstepsincludingt}   \end{figure}\end{document}

I had used this, but it is a super long code and it also compiles very slowly.
