Vizlib Flow Chart Properties- Dimensions, Measures, Sorting, Data Handling

Vizlib Flow Chart supports one measure with multiple dimensions. 

You can add dimensions or metrics dynamically and decide whether they should be used directly or added as alternative dimensions or measures, which can be selected when you're in analysis mode. 


Data - Dimensions and Measures

You can add dimensions, measures, and alternative dimensions and measures in the Data section.

The dimension and measure name are always visible; click the arrow (>) on the right to view its details. 

Click the dots (...) on the farthest right of the dimension or measure name to drag it to a new section.
