[Tex/LaTex] Min, max and average bar chart

pgfplotstikz-pgf

I'm making a chart with min, max and average values for a set of categories. My inspiration is Picture 2. With help from a previous question asked, I've been able to make what's shown in Picture 1.

Is there a way to change the ends of the error bars into other shapes (square, circle), like the ones in Picture 2?

Is there a way to make add labels showing which values are max, min and average, like in Picture 2? ("Landsgjennomsnitt" = average, " … høyest andel" = max, etc.)

Is there a way to add small text next to max and min value of each bar? As shown in Picture 3.

\pgfplotstableread{
x y y-max y-min
{Kategori 1} 9.2 7.3 5.3
{Kategori 2} 11.1 4.3 4.8
{Kategori 3} 12.2  3.5 3.3
{Kategori 4}  12.3  3.7 3.5
{Kategori 5}  21.0 5.2 3.7

yminorgrids,

ticklabel style = {font=\tiny},
x tick label style={rotate=45,anchor=east}
]
\addplot+[blue, very thick, forget plot,only marks] 
plot[very thick, error bars/.cd, y dir=plus, y explicit]
table[x=x,y=y,y error expr=\thisrow{y-max}] {\differanser};
\addplot+[red, very thick, only marks,xticklabels=\empty] 
plot[very thick, error bars/.cd, y dir=minus, y explicit]
table[x=x,y=y,y error expr=\thisrow{y-min}] {\differanser};
\end{axis}

Since you seem to want also legend entries, the simplest option may be to add the corresponding plots.

\documentclass[tikz,border=3mm]{standalone}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\pgfplotsset{compat=1.16}
\begin{document}
\pgfplotstableread{
x y y-max y-min
{Kategori 1} 9.2 7.3 5.3
{Kategori 2} 11.1 4.3 4.8
{Kategori 3} 12.2  3.5 3.3
{Kategori 4}  12.3  3.7 3.5
{Kategori 5}  21.0 5.2 3.7
}{\differanser}
\begin{tikzpicture}[scale=1.3] 
\begin{axis} [
width  = 0.5*\textwidth,
height = 8cm,
symbolic x coords={{Kategori 1},{Kategori 2},{Kategori 3},{Kategori 4},{Kategori 5}},
minor ytick={5,10,15,20,25},
yminorgrids,
xtick=data,
ticklabel style = {font=\tiny},
x tick label style={rotate=45,anchor=east},
legend style={at={(0.05,0.95)},anchor=north west,cells={anchor=west},column
sep=1ex}
]
\addplot+[blue, very thick, forget plot,only marks,forget plot] 
plot[very thick, error bars/.cd, y dir=plus, y explicit]
table[x=x,y=y,y error expr=\thisrow{y-max}] {\differanser};
\addplot+[red, very thick, only marks,xticklabels=\empty,forget plot] 
plot[very thick, error bars/.cd, y dir=minus, y explicit]
table[x=x,y=y,y error expr=\thisrow{y-min}] {\differanser};
\addplot[only marks,mark=*,mark options={fill=blue,draw=red,very thick}] 
table[x=x,y expr=\thisrow{y}] {\differanser};
\addlegendentry{average}
\addplot[only marks,mark=square*,color=blue] 
table[x=x,y expr=\thisrow{y}+\thisrow{y-max}] {\differanser};
\addlegendentry{max}
\addplot[only marks,mark=square*,color=red] 
table[x=x,y expr=\thisrow{y}-\thisrow{y-min}] {\differanser};
\addlegendentry{min}
\end{axis}

[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:

\documentclass{standalone}
\usepackage{pgfplots, tikz}

[Tex/LaTex] Plot with Min/Max bar and two average points

You can use the error bar functionality and combine two \addplot commands to achieve this.

Here are two styles, min max and avg avgopen that you can apply to two \addplot commands to generate the plots like so:

\pgfplotstableread{
Time AvgOpen Avg Min Max
0 7 8 5 10
1 8 7 6 11
2 6 10 5 15
3 8 9 4 10
}\datatable

\begin{tikzpicture}
\begin{axis}[only marks]
\addplot [min max] table {\datatable};
\addplot [avg avgopen] table {\datatable};
\end{axis}

Full code:

\documentclass{article}
\usepackage{pgfplots, pgfplotstable}
\begin{document}

\pgfplotsset{
    min max/.style={
        mark=empty,
        error bars/.cd,
            y dir=plus,
            y explicit,
            error mark=empty,
        /pgfplots/table/.cd,
            x=Time,
            y=Min,
            y error expr=\thisrow{Max}-\thisrow{Min}
    },
    avg avgopen/.style={
        mark=-, mark size=4pt, mark options={xshift=-4pt},
        error bars/.cd,
            y dir=plus,
            y explicit,
            error mark=|,
            error bar style={draw opacity=0,xshift=4pt},
            error mark options={draw opacity=1, mark size=4pt},
        /pgfplots/table/.cd,
            x=Time,
            y=AvgOpen,
            y error expr=\thisrow{Avg}-\thisrow{AvgOpen}
    }
}

\pgfplotstableread{
Time AvgOpen Avg Min Max
0 7 8 5 10
1 8 7 6 11
2 6 10 5 15
3 8 9 4 10
}\datatable

\begin{tikzpicture}
\begin{axis}[only marks]
\addplot [min max] table {\datatable};
\addplot [avg avgopen] table {\datatable};
\end{axis}

\end{tikzpicture}
\end{document}
