Introduction
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
The pre-configured displays are organised in a tree view in the time series display (see example in Figure 1). Each pre-configured display is identified by its name, and may include one or more subplots, each with one or more time series lines.
Figure 1 Example of time series display, showing two sub-plots and tree-view of pre-configured displays
Another option is to plot a longitudinal profile in the time series display (see figure 2). The main difference with the normal time series plot is, that on the X-axis the river chainage is plotted. With the control toolbar a specific time step can be selected.
Figure 2 Example of time series display, showing longitudinal profile.
The display groups are configured by first listing the names of the filters to be shown in the display (for example "Rain gauges", "Gauges" and "Fractions" in figure 3 below) under the displayGroup descriptor. The names of the subplots can then be added (e.g. "MacRitchie" and "Woodleigh" below). Each of the subplots is assigned a plotId which links to the definitions of the plots and the time series set to be used. For example in the Fractions displayGroup a stackPlot is defined with a max and min (this file is attached as an example). Please note that the colours, linestyle, precision etc are defined in the TimeSeriesDisplayConfig.

inverted
This tag can be used to invert the y-axis of a plot. Below a screenshot of an inverted graph. In the example the timeseries with parameter RAIM is inverted.
line
The tag line can be used to configure both single or dual y-axis
Dual y-axis plots
It is possible to have two y-axis visible in the same plot. This can be done by having multiple timeseries where some are assigned to the left y axis and some to the right y axis, or by having a timeseries on the left y axis with an associated rating curve on the right y axis. So every timeseries plot (also in reports) will have a mandatory left y axis to which a timeseries is associated and an optional right y axis to which a timeseries or rating curve is associated.
The display of threshold lines are supported for one y axis. But there can be threshold lines for either the left or the right y axis, but not both.
Multiple TimeSeries plots
To associate a timeseries to the left or right y axis use the <axis> element. This element is optional and leaving it out will associate it (default) to the left axis. Please note that at least one timeseries should be on the left axis (by either settings <axis>left</axis> or leaving the element out and using the default).
Below are two examples of a config and the resulting plot.

Stage/discharge plots
When a discharge is displayed, it is possible to show the stage on the right axis. It is not possible to configure this rating on the left axis (and the timeseries on the right axis), since a plot has to have at least one timeseries on the left axis.
The right axis is then not a linear axis but the ticks on the right axis are calculated from the discharge ticks on the left axis.
It is also possible to display the stage and show the discharge on the right axis. The example below shows a display which plots several discharge time series.
The left axis is a linear axis with ticks for the discharge. The right axis is a non-linear axis.
The ticks on the right axis are calculated from the value of the discharge on the left axis by using a rating curve.

Attributes;

- relativeViewPeriod or season
- nrOfRecentForecasts: Can be applied to show multiple recent forecasts (simulated forecast type)
- ParentLocationId:

- plotId: Link to the plot id
Normally, displays are defined with a relative view period, so that the view window progresses with current system time.
This paradigm does not fit systems that are more oriented towards seasonal or water year analysis. Therefore an option has been added since 2011.02 to define a season, such that the time axis is fixed, while the vertical red line (current system time) moves over time from left to right through the display.
To utilize this functionality, a season should be defined instead of a relative view period. This season specification if composed of a start and end date, as well an entry called 'startForwardLookingPeriod'.
The software compares the currentSystemTime against the date specified in the 'startForwardLookingPeriod' entry, to decide if the time axis needs to shift to the next year/season. This decision is relevant within a water supply forecasting context since a few weeks before the end of the water year you may like to look forward to the next wateryear instead of the current wateryear.
E.g. in the code example below, a wateryear is defined from 1st of October to 30th of September. The startForwardLookingPeriod is defined as 1st of September.
currentSystemTime | view period x-axis (start-end) |

The associated display looks like:
tickTimeStep
To tie the date/time ticks to the valid times of the (cardinal) time step, configure ‘tickTimeStep’ in DisplayGroups.xml. For example, if the ‘tickTimeStep’ is 6 hours then the ticks are always aligned with the synoptic times 00Z, 06Z, 12Z, 18Z. When we are zooming out and there is no space to display all date/times along the x-axis, then one or more synoptic times ticks are omitted. For example we see ticks at 00Z and 18Z.
SubPlotArea
Options available when creating an area type display
Attributes:
- color: Overides other predefined colours
- opaquenessPercentage: Opaqueness expressed as a percentage
- IncludesZeros: When true the zero is always included in the painted extent
Making stacked graphs
Since 2007/02 release the functionality of the SubPlotArea complex type has been extended to include stack plots. The only thing needed to implement this is to add a stackPlot="true" attribute to a subplot element. Attached to this page is a example of this funtionality.
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.
A configuration example of an application of stacked graphs can be find in the how to page How to import and visualize rain and dropsize distribution data from WaterML 2.0 format.
VariableLineWidth
Options available when creating an variable line width type display
Attributes:
- markerColor: option to set marker color different from line color
- lineWidthScaleFactor: factor to increase or decrease the line width
- valueTimeSeriesSet: Time series for XY line plot
- lineWidthTimeSeriesSet: Time series for line width of the XY plot lines
Example
Below a screenshot of a variable line width plot for different ensemble members that have different line width's. In this case line width is an indication of the probability of the ensemble member. The sum of probability of all ensemble members at a time is one. Selecting separate ensemble members will mark them with the color black.
Single location displays can be used to easily create plots for individual locations. This can either be done for individual locations, or alternatively for a locationSet which will then produce a list of location with their corresponding plot.
Chainage location set
(Since 2016.02) By using a chainage location set in a time series set of a plot in the display groups, a longitudinal profile can be plot based on scalar time series for different locations
Notice that it is not possible to combine a longitudinal plot in with a standard plot (having time on the X-axis). Furthermore, it is not possible to use it for relatedLocations, and also thresholds will not be shown.
Single Domain Axis Time Series (1D Spectra plots)
Time series with one domain axis are displayed as one xy chart per time step, like longitudinal profiles. A slider is used to navigate through time.
<timeSeriesSet> <moduleInstanceId>LMW_Import_spectrum</moduleInstanceId> <valueType>scalar</valueType> <parameterId>Wave.variancedensity.meting</parameterId> <domainParameterId>f</domainParameterId> <locationSetId>LMW_Czz10</locationSetId> <timeSeriesType>external historical</timeSeriesType> <timeStep unit="minute" multiplier="60"/> <relativeViewPeriod unit="day" start="-2" end="2"/> <readWriteMode>read only</readWriteMode> </timeSeriesSet>
Dual Domain Axis Time Series (2D Polar Spectra plots)
When a second domain axis is available this will always be used as direction for a polor plot by the time series dialog. When second domain axis is not a directional parameter or the time series has more than two domain axes the time series can not be diplayed the time series dialog with the current functionality

Additional time series
Additional time series can be configured in display group plots. These series are found via attribute functions of the selected time series and the additional time series. When the attribute functions evaluate to the same value the additional time series are added as invisible by default. When additional time series are available the icon of the visibility dialog will change which shows that invisible time series are available and can be made visible.
There is an extra option to show the additional time series in a separate sub plot to make sure there are no plots with incompatible parameter combinations.
Each additional time series element can be given a name, this name will be used as prefix in the legend of the time series and as GroupNode label in the visibility dialog.

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.
