Summary
Confidence limits are vertical lines in the pre-defined displays that are plotted at a position relative to T0 in the graph. The lines can be be configured per subplot in the DisplayGroupsfile. A maximum of three lines can be defined.
Config Options
Configuration per subplot
Part of the schema for the DisplayGroups file is shown below:
To define a forecast confidence line the forecastConfidenceTimeSpan1, forecastConfidenceTimeSpan2or the forecastConfidenceTimeSpan3 element must be defined. Within this element a (time) unit should be defined (e.g. hours) and an optional multiplier or divider. This part of the configuration defines the offset of the line relative to T0.
Configuring the look of the lines
How the lines are drawn in the graphs is configured in the TimeseriesDisplayConfig.xml file in the SystemConfigFiles directory. Within the timeMarkersDisplayConfig element a number of timeMarkerDisplayOptions elements may be configured. See the following example (first in XMLSpy grid view, next as XML):
1.1.3 Configuration Steps
1) Open the DisplayGroups 3.15 default.xml file and go to a subplot:
<displayGroup name="SouthEast Catchments">
<display name="Addlestone">
<relativeViewPeriod unit="hour" start="-24" end="24"/>
<subplot>
<timeSeriesSet>
<moduleInstanceId>MergedPrecipitation_Historical</moduleInstanceId>
<valueType>scalar</valueType>
<parameterId>P.merged</parameterId>
<locationId>2989TH</locationId>
<timeSeriesType>simulated historical</timeSeriesType>
<timeStep unit="minute" multiplier="15"/>
<relativeViewPeriod unit="hour" start="-48" end="24"/>
<readWriteMode>read only</readWriteMode>
</timeSeriesSet>
2) No insert a forecastConfidenceTimeSpan1 element with a unit attribute (hour) just after the subplot element, like this:
<displayGroup name="SouthEast Catchments">
<display name="Addlestone">
<relativeViewPeriod unit="hour" start="-24" end="24"/>
<subplot>
<forecastConfidenceTimeSpan1 unit="hour"/>
<timeSeriesSet>
<moduleInstanceId>MergedPrecipitation_Historical</moduleInstanceId>
<valueType>scalar</valueType>
<parameterId>P.merged</parameterId>
<locationId>2989TH</locationId>
<timeSeriesType>simulated historical</timeSeriesType>
<timeStep unit="minute" multiplier="15"/>
<relativeViewPeriod unit="hour" start="-48" end="24"/>
<readWriteMode>read only</readWriteMode>
</timeSeriesSet>
This should result in a vertical line being draw in the graph:
If the colours of the lines should be changed this can be done in the TimeSeriesDisplayConfig.xml file in the SystemConfigFiles directory.
