Foreign PointID Expression for multiple pointIDs

Question

Hi, 
 Can we use "Iterate function " under "Foreign PointID expression" to be able to plot data from multiple boreholes?

Hi Sapna, 
 I do not believe that will work. The Foreign PointID expression expects one PointID per entity and then extracts the data for that PointID. 
 The Iterate function does not output the entire entity multiple times. It only performs multiple evaluations of the expression you pass to the function. 
 You could write an Iterate function that would return multiple PointID's, but that would not work in a Foreign PointID expression - there can only be one Foreign PointID per entity. Instead, you need to have a separate entity for each Foreign PointID you want to evaluate, as in the example yesterday .
