# Filling region between two \draw Tikz

probably an easy one for people how are used to it. i'd like to fill the area between the two functions with a pattern (stripes, for instance). See the code below. I saw something like this with [domain]-option, but no glue how the scheme works, maybe i'm totaly wrong :D

JOB:

fill diff between red and black funktion

Thanks so far

\begin{tikzpicture}
%Points
\coordinate (x-start) at (0cm, 2cm);
\coordinate (x-end) at (15cm, 2cm);
\begin{scope}[thick]
\draw[] (0,0) -- (0,6);
\draw[] (x-start) -- (x-end);
\end{scope}
\draw[color=red, thick] (0, 1) -- (14, 6);
\draw[color=blue, dashed] (0, 1.75) -- (14, 6.75);
\draw[color=blue, dashed] (0, 0.25) -- (14, 5.25);
%plot
\draw[thick] plot[smooth] file {\dtwData};
\end{tikzpicture}

AFAIK you need to recreate the same paths, i.e. copy the code for the two \draw commands. Try \fill (0,1) -- (14,6) (0,0) plot[smooth] file {\dtwData}. –  Martin Scharrer Jan 26 '13 at 12:28
Thanks, the trick @MartinScharrer worked. The ohter thread is informative as well (at)Benedikt, if found right now an ohter variation fill between two curves in pgfplots –  Alex Jan 26 '13 at 12:36
@Alex: Ok, in this case I posted my comment as an answer. If you accept it the question gets marked as concluded. –  Martin Scharrer Jan 26 '13 at 13:23

You need to recreate the same paths, i.e. copy the code for the two \draw commands, and use the resulting path with the \fill option. Using \fill (0,1) -- (14,6) (0,0) plot[smooth] file {\dtwData} might do it. There are also some option which let you change the rules for filling a path which crosses itself. See the PGF manual for the details.

Here is my finial graphic, FYI

\draw[-latex'] (x-start) -- (x-end);
\draw (13.75,1.7) node[right] {\footnotesize $Zeit$};
\draw (0,5.75) node[left] {\footnotesize $Wert$};
\end{scope}
\fill [color=gray!20, opacity=0.01] (0,0.25) -- (0, 1.75) -- (14, 6.75) -- (14, 5.25) ;
\draw[color=gray, opacity=0.5] (0, 1.75) -- (14, 6.75);
\draw[color=gray, opacity=0.5] (0, 0.25) -- (14, 5.25);
%plot
\draw[thick] plot[smooth] file {\dtwData};
\fill[color = gray!60, opacity=0.1] (0,1) -- (14,6) (0,0) plot[smooth] file {\dtwData};
\fill[pattern color = gray, pattern = north east lines, opacity=0.8] (0,1) -- (14,6) (0,0) plot[smooth] file {\dtwData};
\draw[color=gray, thick] (0, 1) -- (14, 6);

\draw[-latex'] (4, 5) to[out=0,in=90] (6, 3.4);
\draw (3.8, 5) node[left] {\footnotesize $Vergleichsdaten$};
\draw[-latex'] (11.3, 3) to[out=180,in=-90] (7.7, 3.5);
\draw (11.5, 3) node[right] {\footnotesize $Differenz$};
\end{tikzpicture}

Why do you set the text labels in math mode? If you want to use italics then \textit would be better. –  Martin Heller Jan 26 '13 at 21:55
It is quicker and in the final draw, there will be functions. :D –  Alex Feb 3 '13 at 15:08
