Properties - Data and Data Handling

This topic contains the following sections:

• Dimensions

• Measures

• Data Handling

Dimensions

Vizlib Venn Diagram supports and requires two dimensions which represent attributes, and elements. Combined together, attributes and elements provide a set of groupings, intersections and visual representation of relationships.

• Attribute (First Dimension): Is an attribute of elements, like for example hair color, sex, height or age of a student population.

• Elements (Second Dimension): Should represent the number of elements which have one or more attributes assigned to them.

You can find an example of how to add dimensions and a measure to create a Vizlib Venn Diagram in our setup guide here.

When you add a dimension (Figure 1), you can enter a Field, a Label, Include null values, set a Limitation and display unrelated values with Show others, and create an Others label.

Measure

Vizlib Venn Diagram supports one measure which represents the size of the element population. When you add a measure (Figure 2), you can enter an Expression and customize a Label, set the Number formatting and customize the Formatting display by selecting an option from the drop-down.

Data Handling

Data Handling (Figure 3) allows you to set Data Limits, Suppress Zero Values, and set a Calculation Condition, customizing a Display message to show when the condition has not been met.
