Graphics, Figures & Tables ⇒ Bar Chart with small Y-Range

[doeminick]

Hi!

I would like to create a bar chart graphics for which Im using matlab2tikz to generate my output. That has been working fine untill now. Now I want to create a bar chart with relatively small Y-range (ymin=0.996, ymax=1.002), and I get "Dimension too large" error. I checked the pgfplot manual and it states that actually plots with small absolute range can cause this error. So I tried to simply multiply my data by 1000 and later change the Y-Tickz, but I get the same error, even now ymin=996, ymax=1002.

Can someone help me? Thank you .
Here is the original tikz code:

Crosspost to GoLaTeX. Please read, what our administrator thinks about that

If you want to plot in the y range of 0.996 to 1.002, why are you plotting somethin like this:

Code: Select all

\addplot [
color=black,
solid,
forget plot
]
table[row sep=crcr]{
0.5 0\\
4.5 0\\
};

By the way, your code is not compilable without modifications. Please read about Minimal working examples oder Minimalbeispiele (to see a german explanation).

Im sorry, I didnt check the rule about "crossposts". I just wanted to reach as many people as possible, because I need this graphic soon.
So can somebody anyway help me?

It's just that people would like to know if a question is already discussed somewhere else, to save work if it's alread solved there. A simple hyperlink and all is fine. And as you write in German, there' also the question and answer site http://texwelt.de ;-) cross-posts are very welcome there, because of the goal to build a fine indexed German knowledge database based on questions and answers.

I already told you, that the error is caused by the coordinates forming a line. Comment them out and it compiles.

Code: Select all

\documentclass[12pt]{article}
\usepackage{pgfplots}
\begin{document}

\newcommand{\figurewidth}{9cm}
\let\figureheight\figurewidth
%this is not the right way to set a length, tough

In the last few days, many people weren't satisfied with the output of "matlab2tikz.m". The pgfplots package is a very powerful tool. You can export your data as ASCII files and plot it without the intermediate matlab2tikz export. Modifying the looks is much easier this way.

Best regards

Thank you very much for this reply. I am not very familiar, or better to be said not at all few days ago with tikz, thats why I always used this little Matlab-script. I guess Ill try to switch from now on.
