How can already binned data be plotted as a histogram?

I have the following data:

[0, 1000) : 14524
[1000, 2000) : 38214
[2000, 3000) : 36169
[3000, 4000) : 25875
[4000, 5000) : 16942
[5000, 6000) : 10603
[6000, 7000) : 6778
[7000, 8000) : 4288
[8000, 9000) : 2980
[9000, 10000) : 1986
[10000, 11000) : 1392
[11000, 12000) : 1040
[12000, 13000) : 801
[13000, 14000) : 632
[14000, 15000) : 467
[15000, \infty): 3819


How can I plot such data in form of a histogram?

which produces

My main problem is that the bins are centered around the symbolic tikz. They should be in the range noted above.

edit: Obviously I did not express myself clearly. My problem is that the labels of the first bar of the histogram seem to go from -500 to +500. But they should go from 0 to 1000

The other problems (overlapping bars, overlapping of the x-label and the x-tick labels) are not part of the question (although it would be nice if I could get pointers how to fix that).

My suggestion is

Code:

\documentclass[margin=10pt]{standalone}
\usepackage{amsmath}
\usepackage{pgfplots}
\pgfplotsset{compat=1.10}

\newcommand\clipright[1][white]{
\fill[#1](current axis.south east)rectangle(current axis.north-|current axis.outer east);
\pgfresetboundingbox
\useasboundingbox(current axis.outer south west)rectangle([xshift=.5ex]current axis.outer north-|current axis.east);

Explanation:

Your main problem can be solved by using /tikz/ybar interval instead /tikz/ybar. In addition it is necessary to set the compat option at least to 1.3 to avoid the overlapping of xlabel and xtick labels automatically. The current pgfplots version is 1.10.

Code:

\documentclass[margin=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.3}

\begin{document}
\begin{tikzpicture}
\begin{axis}[

\end{document}


But there are some other problems: The last item is missing. This behavoir is explained in the manual. And in addition there is a known issue: nodes near coords generates the last item outside the axis. To solve this problems you can add an additional coordinate (infinite, 3819) and use the workaround from this question:

\documentclass[margin=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.10}

\newcommand\clipright[1][white]{
\fill[#1](current axis.south east)rectangle(current axis.north-|current axis.outer east);
\pgfresetboundingbox
\useasboundingbox(current axis.outer south west)rectangle([xshift=.5ex]current axis.outer north-|current axis.east);
}

Unfortunately I wasn't able to use \infty as a symbolic coordinate without getting error messages.

But it works if I use xtick={1,...,16} and xticklabels instead of symbolic x coords. Then I must change the coordinates to

\addplot[blue, fill=blue!40!white] coordinates {(0,  14524) (1,  38214) (2,  36169) (3,  25875) (4,  16942) (5,  10603) (6,  6778) (7,  4288) (8,  2980) (9,  1986) (10,  1392) (11,  1040) (12,  801) (13,  632) (14,  467) (15,  3819) (16,  3819)};


or use a table

\addplot[blue, fill=blue!40!white] table[x expr=\coordindex,y expr=\thisrowno{0},row sep=\\,header=false]{14524\\ 38214\\ 36169\\ 25875\\ 16942\\ 10603\\ 6778\\ 4288\\ 2980\\ 1986\\ 1392\\ 1040\\ 801\\ 632\\ 467\\ 3819\\ 3819\\};


The result is shown at the top of my answer.

I shamelessly stole from esdd's answer and just changed the design a little bit to make it look less cluttered.

• Thank you! It looks beautiful. It took me a few hours to automate the changes that you made, but now it's part of github.com/MartinThoma/LaTeX-examples/tree/master/tikz/… .

If I understand it correctly the histogram bins are overlapping and you want to fix that. My solution is to adjust spacing of each symbolic coordinate rather than adjusting the bin width.

One solution is to use the x=<dimension> key. It requires some fiddling around with the appropriate dimension; most histograms in fact don't use this compact way of showing histograms but leave some space in between.

Regardless, I've added it to the example below, along with a picture. (Small edit: it appears your last bar was left out in the last plot, so I've fixed that with the key enlarge x limits={true,value=.04}, which enlarges the x limits by 4% on both sides. Picture updated as well.)

If you don't feel like fiddling around with dimensions, use the ybar interval key. It produces pretty much the same result, minus some small spacing differences about the numbers above the bins.

EDIT: this style apparently requires a begin and an end point, which causes the last bar to not be drawn (while the symbolic x-coordinate will be drawn regardless because it's not a numerical value :-(). I'll look into a solution later today.

• I am sorry for not clearly expressing my problem. I wanted to fix the labels of the x-axis (recording time t in ms). They should be for the first bar from 0 to 1000, not from -500 to +500 as it also is the case in your image. Commented Aug 5, 2014 at 12:08
• Can we plot the grid only on the x-axis? Commented Jun 3, 2023 at 7:32
