 \subsection{Generating Charts -- Background Information and Configuration}
 
-%% This section describes the possibilities to configure the
-%% artifact-server. The following properties do affect mostly technical
-%% funtions of the server.
-%% 
-%% This section describes the possibilities in a kind of a reference
-%% manual. Information for the process of installing and integration can be
-%% found in the Administration Manual of the GNV-System (FIXME reference).
-%% The following elements are covered here:
+The artifact-server is able to render different types of charts like 1D
+(timeseries, vertical- and horizontalprofiles, horizontal-cross-section
+profiles (a special case of the horizontalprofiles) and histograms) and 2D-diagrams
+(vertical-cross section profiles). This section describes the
+possibilities to configure different aspects for interpolating of data and
+visualising them in charts.

 \paragraph*{charttemplate}
-{\em Function}: 
+{\em Function}: The chart template is a global template for setting the
+visualization of charts globally like font styles, background, title,
+subtitle, etc. Further information can be found in the configuration
+file referenced via the attribute {\tt configuration}.
 
 \begin{itemize}
-    \item {\tt }:
+    \item {\tt configuration}: path to the configuration XML-file.
 \end{itemize}
 
 
 \paragraph*{palettes}
-{\em Function}: 
+{\em Function}: This section lists the available palettes used for rendering
+vertical-cross-section charts (2D). Each {\tt palette}-element contains
+the following attributes:
 
 \begin{itemize}
-    \item {\tt }:
+    \item {\tt name}: a descriptive name.
+    \item {\tt parameter-ids}: identifier used as keys for matching
+    between data (from the database) and palette. {\bf The {\tt
+    parameter-ids} have to been in sync with the database parameters
+    (normally in {\tt MEDIAN.Parameter})}
+    \item {\tt description}: a description.
+    \item {\tt file}: reference to the defintion of the palette.
+\end{itemize}
+
+For defining ranges for a palette, a range is definied by:
+
+\begin{itemize}
+    \item {\tt index}: Index for accessing the explicit range from the
+    program logic. 
+    \item {\tt from}: lower limit of a range.
+    \item {\tt to}: upper limit of a range
+    \item {\tt rgb}: Red-Green-Blue (RGB) value for rendering the range
+    \item {\tt description}: description for rendering the legend. For
+    special characters use HTML-encoded values like {\tt \&lt;} for $<$
+    or {\tt \&gt;} for $>$.
 \end{itemize}
 
 
 \paragraph*{horizontal-cross-section-profile}
 
-{\em Function}: 
+{\em Function}: Parameterization for the interpolation algorithm for
+horizontal-cross-section-profile calculating the interpolated value
+along the distance.
 
 \begin{itemize}
-    \item {\tt }:
+    \item {\tt samples}: Number of samples calculated for a
+    interpolation along the passed geometric line.
 \end{itemize}
 
 
 \paragraph*{vertical-cross-section}
-{\em Function}: 
+{\em Function}: Parameterization for the interpolation algorithm for
+vertical-cross-sections (2D-charts).
 
 \begin{itemize}
-    \item {\tt }:
+    \item {\tt samples}: Parameters for defining the interpolation grid.
+    {\tt width} for horizontal distances; {\tt height} for the vertical
+    distance.
+    \item {\tt ground}: {\tt interpolation} method for calculating the
+    interpolation from the last measured value against the seafloor.
+    Available methods are {\tt nearest-neighbor | bilinear | bicubic}.\\
+%%    FIXME: Could not find nn and bicubic in the code ...
+    {\tt fill-color}: setting the file color for the seafloor in the
+    diagram.
