You can use the Google Map Polygon object
in your visual dashboard to display query results as a geographic
map polygon.
Before you begin
The Google Map Polygon object properties
are defined in the User's reference section of the QMF help.
About this task
Like the Google Map Polyline object,
the Google Map Polygon object represents a
series of sequential data points. However, instead of being open-ended,
polygons are designed to define regions within a closed loop.
You
can define the characteristics of the polygon edge and the fill area
within the enclosed region.
To insert a Google Map Polygon object:
Procedure
- When you insert the Google Map object,
select Create a map with a component, and then
select the Polygon option on the Define
map content page of the Google Map Wizard.
Then click Next.
- In the All Data Sources tree, select
a table or query, which results you want to use to define a polygon
on the map, and click Next.
- Select the Direct check box to define
the latitude and longitude coordinates of the polygon points and click Next.
- From the Tooltip field list,
select a column to supply a tooltip text for the polygon on the map.
- From the Vertices field list,
select a column to supply the coordinates for the polygon points.
- From the Point format list, select
the format for coordinates (Latitude-Longitude or Longitude-Latitude).
- Select the Encoded check box to
define a polygon in Google Maps encoded format and click Next.
- From the Tooltip field list,
select a column to supply a tooltip text for the polygon on the map.
-
Select the columns to specify a series of points for a polygon from the Points
field list.
Tip: To increase the performance of your visual dashboard, you can use the encoded
polyline algorithm format for your polyline and polygon objects. You can obtain more information
about it from the Google Developers website.
- Click Finish to close the Google
Map Wizard and display the Google Map object
with the polygon that you added to it in the editor.
Tip: To add any other objects to the Google Map object
that you created, add a new Data Template to
it, and then drag the required object from the Map pallet
to the Data Template in the Project
Explorer view.
