Data Viewer

Data Viewer

When you preview data, you view ports in the preview point represented as columns in the Data Viewer.
To identify the hierarchical types, the following punctuation icons are used:
  • [ ] is used to indicate array data type.
  • { } is used to indicate struct data type.
  • <,> is used to indicate map data type.
You can also view tooltips to view the details regarding the type of hierarchical data. If you need to limit the number of ports that appear, you can choose the ports you want to view in the output.
Highlight a field to see the details in the hierarchical type panel. When you right click any hierarchy field, you can export the data in that field in JSON format.
