Pictogram Pie and Bar Chart

Question

For my stats class, I am wanting to be able to make a pictogram (defined for this class as a bar graph with pictures for bars) similar to the ones below if required. A quick google and SE search gives nothing, so I figured I would ask. I have no idea where to start, so I cannot give any code. I do know how to use their normal versions in PGFPlots and pgf-pie, and if possible would like to stay within those packages.

Answer 1

I must answer this!

For the second part, you could clip your pictures.

The "pizza" images used in the \includegraphics of my MWE are from the cook duck of the duck pond with different backgrounds, of course, you'll have to change them into your own images.

\documentclass{article}
\usepackage{tikz}
\usepackage{subcaption}

\tikzset{%
    mynode/.style={draw, circle, very thick, inner sep=1.5pt},
    myseparator/.style={white, line width=1mm},
}

\begin{document}
    \begin{figure}
        \centering
        \begin{tikzpicture}
        \begin{scope}
            \clip (0,0) -- (3,0) arc (0:75:3cm) -- cycle;
            \node{\includegraphics[width=.5\linewidth]{pizzacyan}};
        \end{scope}
        \begin{scope}
            \clip (0,0) -- ([shift={(75:3cm)}]0,0) arc (75:170:3cm) -- cycle;
            \node{\includegraphics[width=.5\linewidth]{pizzared}};
        \end{scope} 
        \begin{scope}
            \clip (0,0) -- ([shift={(170:3cm)}]0,0) arc (170:210:3cm) -- cycle;
            \node{\includegraphics[width=.5\linewidth]{pizzagreen}};
        \end{scope}
        \begin{scope}
            \clip (0,0) -- ([shift={(210:3cm)}]0,0) arc (210:360:3cm) -- cycle;
            \node{\includegraphics[width=.5\linewidth]{pizzablue}};
        \end{scope}     
        \draw[myseparator] (0,0) -- (4,0);
        \foreach \myangle in {75,170,210} {%
            \draw[myseparator] (0,0) -- ([shift={(\myangle:4cm)}]0,0);
        }       
        \foreach \myangle/\myname in
            {40/cyanslice,130/redslice,190/greenslice,290/blueslice} {%
            \node[mynode] at ([shift={(\myangle:2cm)}]0,0) (\myname) {};
        }
        \draw (cyanslice) -- ++(1.4,0) -- ++(.5,.5) node[yshift=.4cm, 
        text width=7em, anchor= north west] {{\LARGE 20\% }\\Prosciutto\\ e funghi};
        \draw (redslice) -- ++(-2,0) -- ++(-1,.5) node[yshift=.4cm, 
        text width=6em, anchor= north east, align=flush right] {{\LARGE 30\% }\\Margherita};
        \draw (greenslice) -- ++(-1.4,0) -- ++(-.5,-.5) node[yshift=.4cm, 
        text width=7em, anchor= north east, align=flush right] {{\LARGE Car\LaTeX}\\Salsiccia e \\ friarielli};
        \draw (blueslice) -- ++(2,0) -- ++(.5,-.5) node[yshift=.4cm, 
        text width=5em, anchor= north west] {{\LARGE 40\% }\\Napoletana};
        \end{tikzpicture}
        \caption*{Preferred pizzas by Italians\\ (no pineapple one on the rankings)}
    \end{figure}

\end{document}

P.S. = The percentages are random.

Answer 2

As a quick hack for the first chart, you could

• borrow the fill stretch image option from tcolorbox
• add every bar as an individual plot

---

\documentclass{standalone}
\usepackage{pgfplots}
\usetikzlibrary{patterns}
\usepackage[skins]{tcolorbox}
\begin{document}
\begin{tikzpicture}
\begin{axis}[ybar]
\addplot [fill stretch image=example-image-b] coordinates {(1,1)};
\addplot [fill stretch image=example-image-b] coordinates {(2,3)};
\addplot [fill stretch image=example-image-b] coordinates {(3,2)};
\end{axis}
\end{tikzpicture}
\end{document}

Answer 3

Another hack for the bar plot drawn in tikz, so you need to draw the tick marks manually. The height of the bar is given in percentage. (Things can be more automated, like counting the number of bars.)

\documentclass[border=5mm]{standalone}
\usepackage{tikz}
\usepackage{graphicx}
\begin{document}
\begin{tikzpicture}[>=latex]
  \newcommand\BarHeight{4}% Max height of bar picture
  \newcommand\BarWidth{1}% Width of bar picture
  \newcommand\Xdist{0.2}% Space between bars
  \newcommand\NumberBars{5}
  \draw[->] (0,0)--(0,\BarHeight cm+0.5 cm);
  \pgfmathparse{\NumberBars*(\BarWidth+\Xdist)+\Xdist+0.2}\edef\lengthxaxis{\pgfmathresult}
  \draw[->] (0,0)--(\lengthxaxis,0);
  \foreach \Num/\Label [count=\ind from 0] in {%
    80/ABC,
    60/CBS,
    40/FOX,
    100/NBC,
    70/ETC}{%
    \pgfmathparse{\Num/100*\BarHeight}\edef\Heightofbar{\pgfmathresult}
    \node[inner sep=0pt,anchor=south west,label=-90:\small\textsf{\Label}] at 
    (\ind*\BarWidth+\ind*\Xdist+\Xdist,0){%
      \includegraphics[width=\BarWidth cm, height=\Heightofbar cm]{example-image}};
  }
\end{tikzpicture}
\end{document}
