UPDATE:

Da bisher keine Lösung erfolgte, habe ich das Thema auch hier gepostet:

Lösung ist unter o.g. Link zu finden.

Hallo zusammen,

anbei mein Minimalbeispiel:

[code]\documentclass{standalone}
\usepackage{pgfplots, pgfplotstable}

\begin{document}

\pgfplotstableread{
Year ICumCDP
2008 3.73E-07
2009 3.35E-07
2010 2.01E-07
2011 3.88E-07
2012 1.36E-06
}\datatable
\pgfplotstablecreatecol[linear regression={ymode=log}]{regression}{\datatable}
\xdef\slope{\pgfplotstableregressiona} % save the slope parameter
\xdef\intercept{\pgfplotstableregressionb} % save the intercept parameter

\begin{tikzpicture}
\begin{semilogyaxis}[
/pgf/number format/.cd,
use comma,
1000 sep={},
log basis y = 10,
ylabel = {ICumCDP},
ymin = 1E-8,
ymax = 1E-4,
xlabel = {Year},
xtick = {2008,2009,2010,2011,2012}
]
\addplot [only marks, blue, x=Year, y=ICumCDP] table {\datatable};
\addplot [no markers, red, domain=2008:2012] {exp(\intercept+\slope*x)};
\end{semilogyaxis}
\end{tikzpicture}
\end{document}[/code]

Die Basis für meinen Code habe ich [url]http://tex.stackexchange.com/questions/69123/how-to-expand-linear-regression-fit-to-the-full-x-axis-range-while-using-semilog[/url] entnommen, wo die Regressionsgrade auch richtig dargestellt wird.

Bei mir hingegen ist die Grade falsch dargestellt.

Gruss,
