Hi ​@SIEBE1 

Based on your question, I assume you are referring to interpolation when exporting the data to Excel only, correct? In visualization, discrete tags should appear stepped (if that’s not the case, there might be some configuration missing in the connector setup).

There have been similar requests to extend the export functionality from other customers, see for example this Product Idea on this Community:

If this fits with your use case, please add your vote to the Idea and leave a comment explaining your specific use case; that way, our Product Team can better evaluate the idea and determine if it fits the roadmap.

If you feel that your question is different from the idea above, you can also share a new Product Idea.

Kind regards,
Jef

It is the case you mentioned, the data is discrete but the visualization of the tag is not stepped. 

​@SIEBE1 I have sent you a private message to request some additional information, so I can look into this a bit deeper.

Based on additional information a support ticket was created for further investigation. We’ll update this topic with the outcome when there is more information.
