General ⇒ pgfplots: How to use a non numeric x axis description?

[Dr.Wackelzahn]

Hi there,
is it possible to draw a bar chart like shown below?
I couldn't find in the pgfplots manual.
Any idea?
Thank you!

Perhaps this could be done with the xticklabel tag. I found an example in the pgfplots documentation that might help. In your case the format of your X axis labels is something like \Alph{\tick} or similar. Generally the documentation gives a lot of examples to get the desired result.


Best regards

Using the example:

Code: Select all

\begin{tikzpicture}
\begin{axis}[
    ybar interval=0.9,
    x tick label as interval,
    xmin=2003,xmax=2030,
    ymin=0,ymax=140,
    xticklabel={$\Alph{\tick}$},
    xtick=data,
    x tick label style={rotate=90,anchor=east,/pgf/number format/1000 sep=}
    ]
\addplot[draw=blue,fill=blue!40!white] coordinates {
    (2003,40) (2005,100) (2007,15)
    (2010,90) (2020,120) (2030,3)};
\end{axis}
\end{tikzpicture}

Doesn't work.
I need something like that instead:

Code: Select all

\addplot{(1,2003-2004,40)(2,2005-2006,15)(3,2007-2009,15)(4,2010-2019,90)(5,2020-2029,120)(6,2030-2040,3)}

or:

Code: Select all

\addplot{(1,A,40)(2,B,15)(3,C,15)(4,D,90)(5,E,120)(6,F,3)}

Generally the documentation gives a lot of examples to get the desired result.

That's right, but I couldn't find an example giving the desired result.
The axis is always a continuing number from left to right with the lowest number left and the highest to the right.

As the following example is almost what I'm searching for, I wounder if it can be realized with pgfplots:

Code: Select all

\definecolor{myblue}{HTML}{92dcec}

\begin{tikzpicture}
 
  \draw (0cm,0cm) -- (15.5cm,0cm);  %Abzisse
  \draw (0cm,0cm) -- (0cm,-0.1cm);  %linkes Ende der Abzisse
  \draw (15.5cm,0cm) -- (15.5cm,-0.1cm);  %rechtes Ende der Abzisse
  
  \draw (-0.1cm,0cm) -- (-0.1cm,4.5cm);  %Ordinate
  \draw (-0.1cm,0cm) -- (-0.2cm,0cm);  %unteres Ende der Ordinate
  \draw (-0.1cm,4.5cm) -- (-0.2cm,4.5cm) node [left] {\%};  %oberes Ende der Ordinate

                              9.5/1.2/Frankreich,
                              11/0.9/Deutschland,
                              12.5/0.5/Portugal,
                              14/0.1/Italien}
    {
     \draw[fill=myblue] (\x cm,0cm) rectangle (1cm+\x cm,\y cm) %die Säulen
       node at (0.5cm + \x cm,\y cm + 0.3cm) {\y}; %die Prozente über den Säulen
     \node[rotate=45, left] at (0.6 cm +\x cm,-0.1cm) {\country}; %Säulenbeschriftung
    };

\end{tikzpicture}

@localghost:
Please tell me the side number where you found a similar example in the pgfplots manual.

[localghost]

Oh, of course. I failed to do that in my previous reply against my habits. It's the middle one on page 70 in Section 7.9 (Tick and Grid Options, p. 63).

[Dr.Wackelzahn]

Well, this one matches nearly, but doesn't work at all.

I have to display data not related by the time on the x axis (days, months, years, or else).

I can't find any example showing the x axis not related by time oder increasing numbers. But I have to use text. How can I get the Text written to the x axis every tick?
Is this possible with pgfplots?

Thank you,
Alex

P.S.: Anyway does this example make sense? The years to the next data are always shown twice (...-2003 ; 2003-...). It always has to be ...-2003 ; 2004-... otherwise it would be counted twice.
I hope this is explained well enough.
P.P.S.: I can't finde Section 34 at http://sourceforge.net/projects/pgf as shown on page 63.
