A geo map overlays your data on a geographic map. You can display your data either as bubbles, as a
scatter plot, or as colored regions on the geo map.
specifies the type of data overlay for the map. Select one of the following values:
Coordinates
displays your data as a simple scatter plot on the map. Each point is located at the
center of a geographic region or at the
coordinates of a location.
Bubbles
displays your data
as a series of bubbles. Each bubble is located at the center of a
geographic region or at the coordinates of a location.
Regions
displays your data
as colored regions on the map.
Note: The Regions map
style is not available for custom geographic roles.
Geography
specifies the geography data item that identifies geographic regions for your map.
Geography data items are identified by the icon.
Bubble size
for the Bubbles map
style, specifies the measure that determines the bubble size.
Color
for the Regions map
style, specifies the measure that determines the regions’ colors.
for the Bubbles map
style, specifies a measure that determines the bubble color.
Specify Properties for a Geo Map
On the Properties tab,
you can specify the following options:
Note: The Title option
is disabled if you select Generate graph title.
Generate graph title
specifies that the graph title is generated automatically based on the data items
in the visualization.
Map service
specifies the source
for the background map.
Size scale
specifies the type
of scaling that is used to draw the bubbles. Select one of the following
values:
Linear
specifies that the
bubble sizes are scaled relative to the minimum and maximum values
(or frequencies) in your data. A negative value is displayed as a
smaller bubble than a positive value.
For the Linear scaling
type, the difference in bubble sizes might not be proportional to
the difference in values.
Magnitude
specifies that the bubble sizes are scaled relative to zero and the greatest absolute value in your data. A negative value is displayed as a circle with a waving edge.
For the Magnitude scaling type, the difference in bubble sizes is proportional to the difference in
absolute values.
Note: This option is available
only for the Bubbles map style.
Frequency
specifies whether the
frequency values are displayed as the number of values (Count)
or as the percentage of values (Percent).
Show map navigation control
specifies whether the map zoom and pan controls are visible.
Color gradient
selects the gradient colors for the visualization.
