groundwater vs time and rain data

I could not get it to work.  I was able to get a compaction curve overlay to work, but I was not able to get rain data (which is not based on POINT) to plot on the same graph using the overlay function with the piezometer data which is POINT based.

You need to use GDW export, not overlay, as the data has a different keyset, best done via a script, for example:

I have all this working in the Datgel Monitoring Tool gINT Add-In, after 2 years of trying I think buying something that works has some ROI.
