[TRNSYS-users] InterpolateData

[David BRADLEY]

Erik,
   Unfortunately there is not an easy way to do that. You would have to 
modify InterpolateData and I suspect you would have to also add a data 
structure to it so that it was able to store the mins and max, then 
communicate them back to the Type that called it. Its an interesting 
idea and I definitely see the benefit. I will certainly add this to the 
list of requested enhancements.
Best,
  David
