| 1 \subsection{Generating Charts -- Background Information and Configuration} | |
| 2 | |
| 3 The artifact-server is able to render different types of charts like 1D | |
| 4 (timeseries, vertical- and horizontalprofiles, horizontal-cross-section | |
| 5 profiles (a special case of the horizontalprofiles) and histograms) and 2D-diagrams | |
| 6 (vertical-cross section profiles). This section describes the | |
| 7 possibilities to configure different aspects for interpolating of data and | |
| 8 visualising them in charts. | |
| 9 | |
| 10 \begin{lstlisting} | |
| 11 artifact-database | |
| 12 `-- gnv # charts, palettes, interpolation parameters | |
| 13 |-- charttemplate | |
| 14 |-- palettes | |
| 15 |-- horizontal-cross-section-profile | |
| 16 `-- vertical-cross-section | |
| 17 \end{lstlisting} | |
| 18 | |
| 19 \paragraph*{charttemplate} | |
| 20 {\em Function}: The chart template is a global template for setting the | |
| 21 visualization of charts globally like font styles, background, title, | |
| 22 subtitle, etc. Further information can be found in the configuration | |
| 23 file referenced via the attribute {\tt configuration}. | |
| 24 | |
| 25 \begin{itemize} | |
| 26 \item {\tt configuration}: path to the configuration XML-file. | |
| 27 \end{itemize} | |
| 28 | |
| 29 | |
| 30 \paragraph*{palettes} | |
| 31 {\em Function}: This section lists the available palettes used for rendering | |
| 32 vertical-cross-section charts (2D). Each {\tt palette}-element contains | |
| 33 the following attributes: | |
| 34 | |
| 35 \begin{itemize} | |
| 36 \item {\tt name}: a descriptive name. | |
| 37 \item {\tt parameter-ids}: identifier used as keys for matching | |
| 38 between data (from the database) and palette. {\bf The {\tt | |
| 39 parameter-ids} have to been in sync with the database parameters | |
| 40 (normally in {\tt MEDIAN.Parameter})} | |
| 41 \item {\tt description}: a description. | |
| 42 \item {\tt file}: reference to the defintion of the palette. | |
| 43 \end{itemize} | |
| 44 | |
| 45 For defining ranges for a palette, a range is definied by: | |
| 46 | |
| 47 \begin{itemize} | |
| 48 \item {\tt index}: Index for accessing the explicit range from the | |
| 49 program logic. | |
| 50 \item {\tt from}: lower limit of a range. | |
| 51 \item {\tt to}: upper limit of a range | |
| 52 \item {\tt rgb}: Red-Green-Blue (RGB) value for rendering the range | |
| 53 \item {\tt description}: description for rendering the legend. For | |
| 54 special characters use HTML-encoded values like {\tt \<} for $<$ | |
| 55 or {\tt \>} for $>$. | |
| 56 \end{itemize} | |
| 57 | |
| 58 | |
| 59 \paragraph*{horizontal-cross-section-profile} | |
| 60 | |
| 61 {\em Function}: Parameterization for the interpolation algorithm for | |
| 62 horizontal-cross-section-profile calculating the interpolated value | |
| 63 along the distance. | |
| 64 | |
| 65 \begin{itemize} | |
| 66 \item {\tt samples}: Number of samples calculated for a | |
| 67 interpolation along the passed geometric line. | |
| 68 \end{itemize} | |
| 69 | |
| 70 | |
| 71 \paragraph*{vertical-cross-section} | |
| 72 {\em Function}: Parameterization for the interpolation algorithm for | |
| 73 vertical-cross-sections (2D-charts). | |
| 74 | |
| 75 \begin{itemize} | |
| 76 \item {\tt samples}: Parameters for defining the interpolation grid. | |
| 77 {\tt width} for horizontal distances; {\tt height} for the vertical | |
| 78 distance. | |
| 79 \item {\tt ground}: {\tt interpolation} method for calculating the | |
| 80 interpolation from the last measured value against the seafloor. | |
| 81 Available methods are {\tt nearest-neighbor | bilinear | bicubic}.\\ | |
| 82 {\tt fill-color}: setting the file color for the seafloor in the | |
| 83 diagram. | |
| 84 \end{itemize} |
