I d like to know if the trend symbol of Coresight 2016 R2 allows to draw archived values as points, without lines and interpolations between them ?
I believe there is no such feature or configuration for that particular display representation (for now).
Jaime is correct. Currently, this is not a supported feature of PI Vision 2017. Please upvote and comment your use case on the enhancement request that Jaime linked to provide feedback to the OSIsoft developers.
If you do not wish to wait for a version of Vision that will have this feature, you can utilize Vision's Extensibility Features to create a custom trend symbol that better suits your needs. Here is some documentation on this:

PI Vision is highly extensible... but you don't have to snake *my* word for it!
