[Tex/LaTex] Horizontal bargraph pgfplot

bar chartpgfplotstikz-pgf

I'd like to make two graphs using TiKz pgfplots or otherwise using this table below. But get the error

! Package pgfplots Error: Sorry, the input coordinate `Bloodstream
Infection (B SI' has not been defined with 'symbolic y
coords={Bloodstream Infection (BSI),S urgical site infections
(SSI),Ventilator-associated pneumonia (VAP),Urinary tra ct infection
(UTI),Others}… Maybe it has been misspelled?.

Have I not correctly defined the names in y coords?

**Type of infection Mean cost   Stdev   St dev Min  Stdev Max   %**
Bloodstream Infection (BSI) 36441   37078   2883    207256  14
Surgical site infections (SSI)  25546   39875   1783    134602  17
Ventilator-associated pneumonia (VAP)   9969    2920    7904    12034   14
Urinary tract infection (UTI)   1006    503 650 1361    33
Others  1000    1000    800 5000    22

When symbolic coordinates are used, the pattern given by symbolic <x or y> coords should match exactly the pattern given in the coordinates. Hence the whitespace before {Others} should be removed.

Moreover, if there are characters such as parentheses or commas in the symbolic coordinate itself that would cause confusion during coordinate parsing of (<some text with ( or comma> , <some text with ( or comma>) they should be put withing brace pairs such that the parser will take them as a group of chars instead of finding a comma and start parsing the next coordinate.

[Tex/LaTex] PGFplot histogram using multiple barplots

There is one problem in your listing: if you say ybar as axis option, pgfplots prepares the overal axis for one or more bar plots - and groups these bars automatically.

This grouping causes your problem "are not on the right spot" (please refer to the reference manual to see the use case for this grouping).

Thus, the main solution is to avoid ybar as axis option. If you write /tikz/ybar, it will work. In this case, the axis is unaware of bar-specific stuff and you can proceed as usual. You may want to add ybar legend (to format the legend as for bar plots) and xtick align=outside explicitly.

The other question "where are my remaining tick labels!?" can be solved by stating which tick positions should be displayed - your choice of xtick=data displays the x coordinates of the first plot. In your case, that is $<-20$,$-20$,$20$,$>20$. A solution would be to provide a "more useful" selection.

Here is a suggestion which has a selection of ticks and two "extra xticks" for the boundaries:

You may want to give a little bit extra space using, say, enlarge x limits=0.01

You can use

 y filter/.expression={y==0 ? nan : y}

in the options of \addplot.
