Hi i am trying to create a screen where i can perform some forecast calculations. This is done in collabaration with the PLC controller and zenon basically sends the parameters to the PLC which calculates the values for at certain timeperiod. Then the operator should be able to add a second time period or reset and start over. I have tried to do this using the extended trend diagram to show the values by saving the answer in a archive. However i dont know how to reset the time period and start over since i isnt able to delete data in the archive.

I have also looked into the report generator and viewer which i also think could do the job. Any one that have this type of setup using one?

Thanksfull for any tips och answer
