Figure 144 Root elements of the gridDisplay configuration
title
Name of the Grid Display. When opened this will appear in the title bar of the window.
defaults
Used to specify attributes that should apply to several gridPlots. Specifying which gridPlots the defaults apply to can be done through parameterGroupId, plotGroupId or plotId. When an attribute that is specified through defaults is needed, FEWS will search for the first defaults that contains the needed attribute and applies to the current gridPlot. If no parameterGroupId, no plotGroupId and no plotId is specified, the defaults is considered to apply to all gridPlots. Note that such a general defaults may override settings made in more specific defaults if it is found first by FEWS, when this occurs try specifying the most general defaults last.
gridPlotGroup
Definition of a group in the grid display. Each group may have its own set of maps and time series to display. Defining groups creates a tree view in the left of the display (see example above). Multiple instances may exist.
...
- id : Id of the display group- this is used in the tree view.
- name : Optional name of the display group- used for reference purposes only
description
Optional description of the display group/grid plot. Used for reference purposes only
highlight
Optional property to highlight the Group name in bold in the selection filter.
gridPlot
Definition of a grid plot within the display group. Each grid plot forms a node in the tree view. When a gridPlot is selected, the appropriate maps will be displayed and the time series data retrieved from the database.
...
Definition of the maps used as a background to the dynamic grid displayed. The layout and zoom extent are also defined in this element. More information on the configuration of the geoMap element can be found here.

classBreaks
Figure 145 Elements of the configuration of class breaks
description
Optional description. Since FEWS 2017.01 it is allowed to have multiple class breaks for a plot. The user can switch between the class breaks with a drop down list. This description is used in the drop down list.
missingValueColor
Not implemented yet.
missingValueOpaqueness
Not implemented yet.
unitVisible (available since build 18734)
When this is true the display unit for the class break values will be displayed in the legend. Default is false. The display unit can be configured in parameter group.
rescaleAroundOrdinalValue (available since build 17892)
Definition of the optional ordinal value that will always keep the same colour when the class break colours are rescaled in the grid display. After rescaling, the highest lowerValue will be changed to the maximum grid value visible in the current zoom extent and the lowest lowerValue will be changed to the minimum grid value visible in the current zoom extent. The lowerValues and the colours in between will be rearranged to fit between the minimum and maximum. Thus the colours for given values change.
If no ordinal value is specified, then the colours are just rearranged. However, if e.g. ordinal value = 0 is specified and 0 values have a white colour, then the rescaling will take this into account so that 0 values always stay coloured white. This can be used for instance when displaying temperatures, where red colours are used for positive values and blue colours are used for negative values and zero values are coloured white.
lowerColor
Colour definition for the colour in the legend associated with the lowest value in the range.
upperColor
Colour definition for the colour in the legend associated with the highest value in the range.
lowerOpaquenessPercentage
Optional definition of the opaqueness of the colour in the legend associated with the lowest value in the range.
upperOpaquenessPercentage
Optional definition of the opaqueness of the colour in the legend associated with the highest value in the range.
lowerSymbolSize
Optional definition of the size of symbols associated with the lowest value in the range.
upperSymbolSize
Optional definition of the size of symbols associated with the highest value in the range.
lowerValue
Definition of the value at which the colour in the grid displayed changes. The legend will be a gradual change in colours from the lowest colour to the highest colour, with the number of increments determined by the number of lowerValue items entered. Multiple entries may exist.
color
Deprecated, use break.
break
The options described above can be used for definitions of lowerValues that have colors that change gradually between a lowerColor and upperColor. The break option can be used instead for specifying a discrete lowerValue with an absolute color, symbolSize and opaquenessPercentage. In this case, set colorSmoothingEnabled to false. Multiple entries may exist. Labels cannot contain the ">" and "<" sign. To present these, use the > and < respectively.
