The Map Visualization renders data that contains latitude and longitude information on a map. You can choose from several tile maps, and configure custom map markers that can show status and icons. The rendering engine is smart enough to render important markers on top of lesser ones. The marker cluster option can show cluster numbers for congested maps with status and zoom options to see the markers. If your data updates over time, an optional auto-zoom feature will keep all of the markers rendered in the window.
This example shows the location of national parks, and the color rules on the pins summarize total number of visitors.
Tip: Double clicking on a Map Visualization will zoom in one level.
Map Tiles and Overlays
Icon Map configuration is broken out into these main steps.
A symbolic name used to represent this Visualization. This is the name that will show up in choosers when adding a Visualization to a Page.
The Tile Provider controls what the map looks like. Each tile set provides its own look and feel, as well as min and max zoom ranges. These ranges are included on the right hand side of the pull-down.
Refer to the Map Tiles and Overlays section for more information.
Choose the minimum zoom level that the map is allowed to show. This option is only enabled when you choose No for Default Zoom Levels.
Choose the maximum zoom level that the map is allowed to show. This option is only enabled when you choose No for Default Zoom Levels.
This sets the default zoom level for the map.
This sets the Latitude for the center point of the map.
This sets the Longitude for the center point of the map.
Determine the placement of the zoom control on the map.
Enables options for looking up current location based off an address.
Choose the attribute in the data that will contain the Latitude of the marker to place. Value is expected in decimal format.
Choose the attribute in the data that will contain the Longitude of the marker to place. Value is expected in decimal format.
Determines whether icons will be combined together based on proximity.
Define a static or rule based icon to place on the marker.
This step is enabled on step Markers, when “Use Clustering?” = Yes.
If Heap Map option is turned on, then no clustering will be done.
This step is enabled on step Markers, when “Show Label?” = Yes.
This option is configured in the “Marker Labels” menu, which is activated when “Use Label?” is set to Yes.
Choose the attribute from the data that contains the value to be used with the label.
Configure a text formatter for the label.
This will appear if, in the “Markers” Section, the Formatter Type property is set to Derived From. The legend’s colors and labels will be rendered from the derived rules’ color and label. See Rule Sets for more detail.
The location of the Legend box on the map.
Available when “Position” is not set to None. Optional title for the legend box.
Available when “Position” is not set to None. Determines the text color of the legend’s title and key labels.
Choose which weather layers you would like to enable by turning “Enable Layer” column switch to Yes. Choose Yes for “On by default” if you would like the layer to be visible on a newly initialized map. If you choose No for “On by default”, the user can enable the layer manually on the visualization later. Layer Opacity allows you to change the translucency of the layer.
The radius (in pixels) of the Heat Map brush.
A numeric value that defines the minimum opacity of a heat point.
A numeric value that defines the maximum opacity of a heat point.
A numeric value that adjusts how much a heat point is blurred.
(This option is displayed when “Use Aggregation?” is set to Yes.)
Choose a field to aggregate a value for heat.
Displays a preview of the Map.
