C.4.3.6. Map Properties
Pre-load Contextual Layers?
By default, the contextual layers in a Flash report only load at the point
where the toggle box for a layer is clicked in the Map Layers box.
However, it is possible to configure a Flash report so that contextual layers
are pre-loaded (i.e. the vector graphics are loaded in when the report
initially loads. This, however, does not necessarily mean that the layers
will also be visible in the map by default. It simply means that the report
‘knows’ the vector graphic when the report is opened. You will need to
ensure that contextual layers are pre-loaded if you are implementing filter
map zooms (i.e. you have linked filter values to polygons in your contextual
layers so that applying a filter in the report zooms in the map). Simply
check the ‘Pre-load Contextual Layers?’ box in the Map Properties in the
Designer.
Visible Contextual Layers List
If you wish contextual layers to be visible (i.e. switched on in the Map
Layers box) when a report opens you must edit the ‘Visible Contextual
Layers List’ property. When you click the ‘Value’ column for this property a
popup window will appear. The vector contextual layers in a report have
IDs of contextualLayer1.swf, contextualLayer2.swf, contextualLayer3.swf
and so on. If you wish the lowermost layer in the vertical stack (i.e.
contextualLayer1.swf) to be visible by default you enter the value
‘contextualLayer1’ for the ‘Visible Contextual Layers List’ property. If you
want the lowermost two layers to be visible by default you enter the value
‘contextualLayer1,contextualLayer2’ and so on. If you are unsure of the
contextual layer ‘id’ you wish to make visible by default you can refer to the
map.swf.xml file in the output folder of your dynamic report. This file can
be viewed using a text editor (e.g. Textpad). Contextual layers will have an
entry in map.swf.xml similar to the following:
The config.xml file of an HTML template does not currently include
this property. This means that if you have set up filters that should
zoom to the filtered areas, the map will only zoom if the relevant
contextual layer is either visible when opening the report or after it
has been toggled on.
Other important table properties in the HTML templates are:
Exportable?
If this box is ticked you will see an export button in the top right hand
corner of the table when you hover with the mouse over it. Clicking
this button will open a new browser tab/window in which you will be
able to copy and paste the data in a comma delimited CSV format.
Zoom On Selection?
If this box is ticked the map will zoom to the feature which gets
selected in the data table
Show Legend Colour?
If you do not wish to see circles with the legend colour of each
feature in the table you can untick this checkbox.
