On the ‘Edit, Chart’ screen, click the ‘Chart’ tab and choose ‘Chord Diagram' from the list of chart types.
To create a Chord Diagram, you will need to add the following information on the Data tab, the 3 required pieces of data are all dimensions:
Identifier - this is a field that links the nodes together such as a Service Desk ticket number.
Node - such as an Employee Name
State - such as Job Role
You will also be able to specify drill conditions for Chord Diagrams, please refer to this section for more information.
Drilling on this chart uses a IN filter to group multiple items (this is different from other charts). For example, if you drill on a ‘Jon’ Node, the Filter will include all links from any other node to ‘Jon’, and all links from ‘Jon’ to any other node:
Dependency Charts Pi Employee Name IN Jon::::Ming::::Leah
Dependency Charts Pi Role IN Consultant::::Developer
Dependency Charts Pi Ticket Id IN 1::::3::::4::::5
Drilling on the link from ‘Jon’ to ‘Leah’, the filter will include only the information from that link:
Dependency Charts Pi Employee Name IN Jon::::Leah
Dependency Charts Pi Role IN Consultant::::Developer
Dependency Charts Pi Ticket Id IN 3::::4::::
