How to Format a Geospatial Service Visualization with Markers

There are several options for formatting a geospatial service visualization that displays image or bubble markers.

Select the objects you want to format.
Right-click and choose Format.

A pop-up menu displays the appropriate formatting options for that object. In addition, the Format panel automatically updates the first drop-down list with the area of the visualization you are formatting and the corresponding format options appear.
Select the appropriate options to format the object. See Format Panel for Geospatial Service Visualizations for more information about the options on the Format panel.
In the Format panel, select Map Options from the first drop-down list.
In the Map Style drop-down list, select the display theme to apply to the map.
In the Zoom behavior drop-down list, select options for zoom behavior when selecting locations on the map.

Select Static to keep a static level of magnification. When this option is selected, you can also check the Remember zoom level checkbox to maintain the current level of magnification.

or

Select Dynamic to zoom in on and refit the contents of the visualization.
If your map contains multiple layers, select Zoom through layers to adjust the zoom level for each layer using the sliders, ranging from World to Street. Right-click a slider thumb and select whether to include or exclude layers. Hover over a thumb to view the zoom level. Adjust the default zoom level of the map using the slide ruler.

Your map has three layers. The first, bottom layer, contains map markers for cities throughout the world. The second layer contains areas for states or municipalities within a country. The third, top layer, contains areas for countries. You can zoom in past country areas, to view only state areas, and then finally view only cities with map markers.

Select the More Options link at the bottom of the Format panel to open the More Options dialog and specify additional formatting options for displaying visualization data.
Select Formatting on layer from the first drop-down list.
If your visualization contains multiple layers, select the layer you want to format from the second drop-down list.
In the Type drop-down list, select Marker or Bubble to display a map with image or bubble markers.
You can cluster a large number of map markers together to form a circle. Select the Enable Clustering checkbox and select options for clustering map markers.
Use the slider to set the zoom level for clustering.
Enter the radius size, in pixels, that you want to use for clustering in Cluster radius.
You can color map markers in the visualization, based on metric values or attribute elements.

To color map markers based on metric values or attribute elements, place one metric or attribute in the Color By area of the Editor panel. The legend reflects what color is attributed to each metric value or attribute element.
You can color map markers in the visualization, based on the value of a metric, by defining a threshold on the metric used to display the map markers. See Create a Threshold on a Metric Using the Quick Thresholds Editor for more information.
You can apply general formatting options used for all types of visualizations, such as renaming attributes or metrics, choosing whether to display a visualization's title bar, etc. See Format Dashboards and Visualizations for more information.
