Start with an empty presentation. Insert a SmartArt diagram of type "Radial Cluster". Enter some dummy content, e.g. the words Center, Top, Right, Left. Save the file.

Unpack the file and examine layout1.xml. You will find attributes axis="ch ch" or ptType="node node node" or cnt="1 3 0". Such values are not allowed in the standard. And it is not clear how they are interpreted. If you use an extension to the standard, please document it. If an extension to the standard is not intended, please fix the "Radial Cluster" template.

Hi  Regina Henschel

Based on my research, the attributes ptType, cnt, and axis can each represent either a single value or a list of values.

With this in mind, it helps explain why scenarios such as axis="ch" can appear as a single value, or axis="ch ch" may represent a list of values within the same attribute. 

 

 

To better interpret these values, I found the following documentation that may provide additional reference and context:

However, there should ideally be the latest official documentation that clearly explains this. 

That said, I highly recommend sharing your feedback through Ideas · Community.

I hope this brings some additional insight.
