Working with Simple Bubble Charts
A Simple Bubble Charts allow you to compare objects of the same type, by analyzing three levels of data and using the values to affect the size and position of the representations on the chart.
One value is used to position the bubble on the X-axis, another value is used to position the bubble on the Y-axis, while the size of the bubble is based on the third property.
With its accompanying Data Quality Chart, it also enables you to see where your data is incomplete, by highlighting objects that do not have values set for the properties you are referencing.
If you want to use a Bubble Chart that visualizes data from associated or indirectly associated objects, see Working with Cluster Bubble Charts.

The Simple Bubble Chart requires three properties to compare - and these must all be either Whole Number or Decimal Number properties - or they can be Drop-Down properties where the Abbreviation contains a number. |

Why and how should you use one?
You should use a Simple Bubble Chart when you want to visualize a comparison between objects based on three properties.
A typical example would be to have some Application objects with three useful properties:
-
Cost - a Whole Number property to represent the monetary cost of the application
-
Business Alignment - a Drop-Down property ranging from '0 - Unknown' to '5 - Very High', which represents how important the application is to the business
-
IT Alignment - a Drop-Down property with the same range as Business Alignment, which represents how well aligned the application is to your current IT infrastructure, support and competencies
In this example the IT Alignment is used as the X-axis, the Business Alignment is the Y-axis, and the size of each bubble is based on the Cost.
Where and when can you use one?
Use the table below to see where you can use a Simple Bubble Chart:
|
Page Type |
Parent node |
Tabs |
Number on page |
Editable |
|---|---|---|---|---|
|
Index Page |
Object Type node |
The chart must be in a Tab, but there can only be one Tab |
The Bubble Chart must be the only item on the page |
No |
What would you like to do?
Add a Simple Bubble Chart to your page
|
|
These instructions assume you have an Index Page node, containing a Tab Controller with one Tab that includes an Object Type node. The result will be an Index Page including two Tabs, one which you created and named yourself and that holds the Bubble Chart, and the second which is automatically created and is used for the Data Quality Chart. |

-
Select the Object Type node and ensure all the properties you want to reference are selected in the Selected Properties area
-
If you want to filter the list of objects displayed, use the Filter Properties area to apply any filtering
-
Switch the Layout node beneath the Object Type node to Empty
To do this: Right-click the Layout node and choose Switch Layout > CW > Empty
-
Add the Bubble Chart (Simple) behavior to the Layout node
To do this: Right-click the Layout node and choose Add Behaviors > Bubble Charts > Bubble Chart (Simple)
A Dashboard Bubble Chart node is added
-
Select the Bubble Chart (Simple) node and configure the following settings:
-
Use the Node Name to set the title of the chart as it appears in the web page
-
Use Circle to specify the Scriptname of the property you want to use to affect the size of the bubble
Always use lower case when referring to Scriptnames
-
Use X to enter the Scriptname of the property you want to use on the X-axis
-
Use Y to enter the Scriptname of the property you want to use on the Y-axis
-
Use the three Data Quality settings to choose whether the corresponding properties are Drop-Downs (Lookups) or number properties
Choose 'Lookup_Abbreviation_Not_o' if the property is a Drop-Down
Choose 'Not_Equal_To_o' if the property is a number
-
Use Circle Unit to specify the text to be displayed on the chart for the bubble size value
-
Use X Unit to specify the text to be displayed on the X-axis - leave blank to use the Property Type Name
-
Use Y Unit to specify the text to be displayed on the Y-axis - leave blank to use the Property Type Name
-
Use Circle Intersection Object Type to specify the Scriptname of the Object Type used on the Object Type node
