# Bar plots with small x-values

I'm trying to make a bar chart with really small x-increments. I used this code:

    \begin{axis}[ymin=0, ymax=30, minor y tick num = 5, area style,]
\addplot+[ybar interval,mark=no] plot coordinates { (0.13, 15) (0.191, 17) (0.252, 26) (0.313, 3)
(0.374, 3) (0.435, 3) (0.496, 5) (0.56, 0)};
\end{axis}
\end{tikzpicture}


Which produced this picture:

The problem is that the numbers that appear under the x-axis have nothing to do with the numbers I want to plot. I think the bars are in place, it's just that the numbers that show up are 0.1, 0.2, 0.3, etc. but my plot starts at 0.13 and has increments of 0.061 . I would like those values to appear (i.e. 0.13, 0.191, 0.252, and so on) instead.
I have tried defining xmin and xmax values and definig the xbar interval, but nothing seems to work. I would really appreciate any help.

• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Stefan Pinnow Jun 23 at 6:47

To achieve what you want you just need to add xtick=data to the axis options. To show more than two decimal places you need in addition to adapt the x tick label style. For details please have a look at the comments in the code.
