The plot display is used to show scalar time series. Each topology node is connected to a display group. After selecting a topology node the first plot of that display group will be shown automatically. If there is already a node selected then Delft-FEWS will first to try to find a plot with the same location and parameter as currently displayed if that is not possible then the first plot will be displayed.

...

The forecaster help panel shows user provided documentation which is available for a node. Currently the following formats are supported: text-files, images and pdf-files. Users can place documents in a directory within predefined directories.
These directories can be configured in the topology.xml configuration file by adding a forecasterHelperDirectories element that contains a directory element for all directories.

For instance:

<forecasterHelperDirectories>
   <directory>d:\Data\ForecasterHelperData\</directory>
   <directory>d:\Data\FHD3\</directory>
</forecasterHelperDirectories>

If this is not present in the topology.xml the directory in the global.properties defined by the INFORMATION_PANEL_FOLDER property will be used. Within these directories each node has its own directory. The directory should have the same name as the node id.
Within that directory the documentation for that node can be placed. If you make use sub-folders, make sure to also include the main folder as a directory when you list the <forecasterHelperDirectories>. Documents in the folder configured as <allNodesDirectory> will be visible at all nodes.

<forecasterHelperDirectories>
	<directory>$DOCUMENTS_ROOT_FOLDER$</directory>
	<directory>$DOCUMENTS_ROOT_FOLDER$/subfolder_1/</directory>
	<directory>$DOCUMENTS_ROOT_FOLDER$/subfolder_2</directory>	
	<allNodesDirectory>$DOCUMENTS_ALWAYSVISIBLE_FOLDER$</allNodesDirectory>-->
</forecasterHelperDirectories>
