This section is very short and needs to be extended (with examples). Also the new method (defining plots) is not clear
A list of pre-configured displays can be configured in the Display groups. When available on the file system, the name of the XML file is for example:
DisplayGroups 1.00 default.xml
DisplayGroups Fixed file name for the explorer settings
1.00 Version number
default Flag to indicate the version is the default configuration (otherwise omitted).
The pre-configured displays are organised in a tree view in the time series display (see example in Figure 17). Each pre-configured display is identified by its name, and may include one or more subplots, each with one or more time series lines.

description
A description of the display groups configuration. Used for referencing only.
displayGroup
Root element for each displayGroup. A display group forms one of the main nodes in the tree view and may contain multiple displays. Multiple display groups may be defined.
Attributes;
- name: name of the display group (used in the tree view)
display
Definition of a pre-configured display. Each display may contain multiple sub-plots. Multiple displays may be defined per display group.
Attributes;
- name: name of the display (used in the tree view)
Figure 19 Elements in the Display section of the DisplayGroups configuration
subplot
Root element for each subplot. Multiple sub-plots may be defined per display.
timeSeriesSet
Definition of the time series set to be displayed. See section 3.3 for a description of the time series set definition.
Display groups may be defined while DELFT-FEWS is running and reloaded by re-opening the time series dialogue. If a mistake is made, then the shortcuts item to open the tree view will not appear and an appropriate message will be generated. After resolving the mistake the item will again become available on re-loading the display.
Making stacked graphs
Possible as of 2007/02 release.
The only thing needed to implement this is to add a stackPlot="true" attribute to a subplot element. An example is given below:
Example config. file (from DisplayGroups.xml) :
<subplot stackPlot="true">
<timeSeriesSet>
.........
</timeSeriesSet>
<timeSeriesSet>
..........
</timeSeriesSet>
</subplot>
If stackPlot is True, the timeseries of this subplot are plotted as stacked areas, except for the timeseries that are specified inside the (optional) element <area>. Area-series are always plotted as so called 'difference area'.
Attribute stackPlot is intended as overruling of the default series paint (i.e. line or bar)
It is not possible to combine 'stacked areas' and lines/bars in one plot.
