Use this dialog to specify the formatting of bubbles on a map. Bubble size represents the value of a metric. Bubble location indicates the geographic region. Bubbles, images, and shapes can apply to both polygon layers and point layers. Point layers cannot use a color fill format.
For more information, see "Editing Map Views".
This dialog is also displayed as:
Components
Name
Displays the name of the data column whose values are displayed as bubbles, color fills, images, lines, or shapes on the map and used as their label.
Name Automatically
Use this box to specify whether you want to enter the label for the bubbles, color fills, images, lines, or shapes, rather than having the label specified automatically as the column name.
X (longitude) and Y (latitude)
Available only for the custom point layer and only if the Single Column box is not selected. Use this list to select the columns whose values specify the longitude and latitude of the point to represent on the map as a bubble, image, or shape.
You must specify different columns for longitude and latitude. These columns must store longitude and latitude values, values from a coordinate system that can identify a point, or address values that can be converted to longitude and latitude using the ETL system. The column values must adhere to the WGS84 coordinate system.
Single Column
Use this box to indicate that the values from one column specify the coordinates of the points to represent on the map. The column is specified in the Location box.
Location
Available only for the custom point layer and only if the Single Column box is selected. Use this list to select the column whose values specify the longitude and latitude of the point to represent on the map as a bubble, image, or shape. Ensure that the column contains both longitude and latitude values and that the values are stored in (Longitude, Latitude) order. If the values in the column are stored in (Latitude, Longitude) order, then the formats are displayed at incorrect locations.
Delimiter
Available only for the custom point layer and only if the Single Column box is selected. Use this box to enter the delimiter that is used in the single column that you specified in the Location box that holds the longitude and latitude values, such as a comma. This box has no default values. If you do not specify the proper delimiter, then the format cannot be displayed appropriately on the map.
ToolTips
Use this list to select the column whose name is used as the tooltip when you hover over a value of the data column on the map.
Shape
Available only for shapes. Use this list to select the shape to include on the map. You can select Circle, Triangle, or Diamond.
Vary Size By or Vary Color By or Vary Image By
Use this list to specify the measure column whose values control the lines, the images, the color fills, or the size of the bubbles or shapes, such as Dollars or Units. For example, you can vary the color of the shapes by one measure column and the size of the shapes by another measure column.
The following formats have specific attribute associations:
Vary Size By and Vary Color By apply to shapes and bubbles.
Vary Image By applies to images.
Vary Width By and Vary Color By apply to shape lines.
Minimum Size
Available only for bubbles and shapes. Enter the minimum size of the bubbles or shapes.
Maximum Size
Available only for bubbles and shapes. Enter the maximum size of the bubbles or shapes.
Color
Available only for bubbles and shapes. Use this list to select the color for the bubbles or shapes on the map. For shapes, this box is disabled when you click Vary By Measure. When varying color by measure, you specify a palette of colors that corresponds to the binned values of the measure.
Bin Type
Use this list to select the type of grouping for the values to indicate using images, lines, or shapes. You can select one of the following types:
Percentile Binning — Group geographies by their rank, such as the top 33%. Percentile threshold values are specified automatically; you cannot modify them.
Value Binning — You specify the minimum and maximum values for each of the groups.
Continuous Color — For color fill only. A gradient of color is varied and applied to the ranks of the geographies. You make no specifications for minimum and maximum values.
Bins
Use this list to select the number of bins for grouping the values to indicate using color fills, images, lines, or shapes. You can select various integers, Quartile (4), or Decile (10). The number of bins that you select corresponds to the number of colors that the map format shows.
Style
Available only for lines, shapes, and color fills. Use this list to select the shape or gradient to display. The number of colors in the style depends on the number that is specified for Bins.
Minimum and Maximum
Use these boxes to enter the minimum, maximum, and other values for the bins. You can enter the values only if you select Value Binning for Bin Type. If you select Percentile Binning, then the values are specified automatically.
Label
Enter the labels for the bins. Labeling a bin helps users understand what a particular bin, or bucket, means. A label for the top quartile might say "Top Selling Products" instead of "Top 25%". You can customize these labels, and the map provides automatic bin labels for particular types of data sets (percentage bins).
Image
Available only for images. Use this list to select the images for the bins. Click an image to display the "Select Image dialog" where you select the image for the bin. Images are shown at a latitude and longitude coordinate.
Color
Available only for color fill and lines. Use this list to select the colors for the bins. Click a color to display a dialog where you select the color for the bin.
Allow Dashboard Users to Edit Thresholds
Available only for color fill and lines when Bin Type is set to Percentile Binning or Value Binning. Select this box to display a slider component that enables end users to dynamically adjust threshold values. These adjustments allow users to perform visual analysis on their map data, which is sometimes referred to as "what-if analysis."
If you allow users to edit thresholds and they modify them, then the setting for Bin Type is automatically changed to Value Binning from any other settings.
This option is not available when Vary Width By Measure is selected.
For information, see "Modifying Thresholds for Formats on a Map View".
Transparency
Available only for bubbles, color fill, and shapes. Specifies how transparent the format is when applied to the map. You specify transparency as a percentage that ranges from 0 through 100. The default is 25%. A value of 0% renders the format as a solid color, which is fully opaque. A value of 100% results in the format being invisible. The effects of the transparency setting can be optically measured by the visibility of the checkered background in the Style and Color boxes of this dialog.
See the Notes section for more information about how the Transparency field works in relation to label layers.
Line Width
Available only for lines. Specifies the width of the line in pixels. The default value is 8, while the minimum value is 1 and the maximum is 16.
This option is not available when Vary Width By Measure is selected.
Vary Width By Measure
Available only for lines. Use this check box to specify whether the width of a line for a measure will vary. When this check box is selected, Line Width and Allow Dashboard Users to Edit Thresholds are disabled.
Vary Width By
Available only when Vary Width By Measure is selected for a line. Use this list to select the measure whose line thickness you wish to vary.
Minimum Width
Available only when Vary Width By Measure is selected for a line. Enter a number in pixels that represents the minimum width for the line.
Maximum Width
Available only when Vary Width By Measure is selected for a line. Enter a number in pixels that represents the maximum width for the line.
Notes
When you specify a value in the Transparency field, you must be aware of the label layers that are in use. By default, label layers are added for every visible layer on the map. You switch labels on or off using the "Map Properties dialog: Labels tab".
When a label layer is applied to a map, the layer uses the style that was defined in Oracle Map Builder. This style might be opaque, which blocks the map from being displayed in its entirety. If you then try to apply a transparent format to that map, the display of the map is still blocked. To ensure that format transparency is not blocked, do one of the following:
Ensure that the style for the layer does not use an opaque color fill.
Hide the opaque label layers using the Labels tab of the Map Properties dialog.
