Show my results bar chart in latex

Question

I have a results of my research in the form of a bar chart created from excel work sheet. The image of my excel sheet and bar chart is given in the figure below;
Please help me with code, I am new to latex and never draw these kind of bar charts earlier. Thanks in advance.

Answer 1

This is an attempt, where the data is read in via pgfplotstableread, since the data has two parallel axis label, a way to work around is to draw the plot twice and change the xticklabelon the second plot. Furthermore, this solution applies shadows.blur from tikzlibrary to have the shadow effects in order to mimic the shadow effect in the OP. the parameters x/yshift below can be changed to meet your need. As can be seen in the OP, the second labels were overlapped and this is improved by the width=15cm in the axis options, which can also be adjusted to meet one's need.

blur shadow={shadow yshift=0pt, shadow xshift=2pt}

Code:

\documentclass[border=10pt]{standalone}
\usepackage{pgf,pgfplots}
\usepackage{tikz,pgfplotstable}
\pgfplotsset{compat=1.8}
\usetikzlibrary{arrows,automata,calc,shapes, positioning,shadows,shadows.blur,shapes.geometric}
\begin{document}
\definecolor{darkblue}{HTML}{003366}
\def\mystrut{\vphantom{pb}}

\pgfplotstableread[col sep=comma]{
items,section_1,section_2
max,centroid,82
max,bisector,82
max,mom,84
max,lom,84
max,som,71
sum,centroid,82
sum,bisector,82
sum,mom,80

sum,som,71
