I am trying to stop using Excel charts in my academic papers and rather use something more LaTeX integrated such as Tikz.
My current Excel chart looks like that:
![I have]()
As can be seen, any combination from the two sets {CR, ER, CRER} and {10, 50, 100} contains four information: Avg, AvgOpen, Min and Max.
I would like to draw, for each combination, one single bar: One bar that spans from Min to Max and two different points that indicate Avg and AvgOpen.
Searching on the web, the closest to what I want looks like that:
![I would like to have]()
However, I could only find solutions like the one discussed here:
Link to other discussion thread:
pgfplots with symbolic x coords and error bars
In this example, the min and max values can be well identified, but there is only one single point to indicate the avg. How could I add another point to such an example?
Also, in the Excel chart you can see that I have two lines of labels on the x-axis. For example a “CR” which is then sub-divided into 10, 50 and 100. Does anybody have an indication how I could create such a chart?
Many thanks in advance. Any kind of help is appreciated.

==========================================
I managed to build a chart according to what I would like to have. Now I just have to add a legend, which does not quite work out. Using normal bars, I can add a legend. However, using error bars I didn’t yet figure out how. Please consider my current code:
newcolumntype{C}[1]{>{centeringarraybackslash}p{#1}}
pgfplotsset{
min max/.style={
mark=-,
error bars/.cd,
y dir=plus,
y explicit,
error mark=-,
/pgfplots/table/.cd,
x=Time,
y=Min,
y error expr=thisrow{Max}-thisrow{Min}
},
avg avgopen/.style={
mark=*, mark size=2pt, %mark options={xshift=-2pt},
error bars/.cd,
y dir=plus,
y explicit,
error mark=square,
% error mark=|,
% error bar style={draw opacity=0,xshift=3pt},
% error mark options={draw opacity=1, mark size=3pt},
/pgfplots/table/.cd,
x=Time,
y=AvgOpen,
y error expr=thisrow{Avg}-thisrow{AvgOpen}
}
}
pgfplotstableread{
Time Avg AvgOpen Min Max
CR 8.63 5.81 4 10
ER 8.17 6.31 3 10
CRER 8.42 5.84 4 10
}datatableA
pgfplotstableread{
Time Avg AvgOpen Min Max
CR 25.02 15.84 6 44
ER 23.17 16.97 6 43
CRER 24.15 15.73 6 45
}datatableB
pgfplotstableread{
Time Avg AvgOpen Min Max
CR 48.24 38.18 13 86
ER 45.47 39.41 12 82
CRER 47.19 38.29 12 85
}datatableC
begin{figure}[htbp]
hspace{-0.5cm}
begin{tabular}{C{.26textwidth}C{.26textwidth}C{.26textwidth}C{.20textwidth}}
%%%%%%%%%%%%%%%%%%%%%%
subfigure [10 loc] {
begin{tikzpicture}
begin{axis} [symbolic x coords={CR,ER,CRER},xtick=data,width=0.30textwidth,height=0.4textwidth,
%legend entries={Min, Max, Avg, AvgOpen},
%legend to name=legend:legend-stats1
legend pos=north west,
]
addplot [min max][forget plot,only marks] table {datatableA};
addplot [avg avgopen][forget plot,only marks] table {datatableA};
%legend{$S$};
end{axis}
end{tikzpicture}
} &
%%%%%%%%%%%%%%%%%%%%%%
subfigure [50 loc] {
begin{tikzpicture}
begin{axis} [symbolic x coords={CR,ER,CRER},xtick=data,width=0.30textwidth,height=0.4textwidth]
addplot [min max][forget plot,only marks] table {datatableB};
addplot [avg avgopen][forget plot,only marks] table {datatableB};
end{axis}
end{tikzpicture}
} &
%%%%%%%%%%%%%%%%%%%%%%
subfigure [100 loc] {
begin{tikzpicture}
begin{axis} [symbolic x coords={CR,ER,CRER},xtick=data,width=0.30textwidth,height=0.4textwidth]
addplot [min max][forget plot,only marks] table {datatableC};
addplot [avg avgopen][forget plot,only marks] table {datatableC};
end{axis}
end{tikzpicture}
} &
%ref{legend:legend-stats1}
end{tabular}
caption{My chart.}
end{figure}
This gives me a chart such as the following one:
![My chart]()
Now, I would like to add a legend to the right of the 3 subfigures, vertically aligned in the center or at the top, with the following four entries (showing the corresponding symbol):
- Min
- Max
- Avg
- AvgOpen
Furthermore, I would like to have a little less (horizontal) space between each of the bars.
As mentioned, I was trying to manage this since some time now and I just don’t find the right commands.
Any help is appreciated! Many thanks in advance.
