Does the "TERR Points in Polygons Data Function" dxp work with shapefiles that are not WGS84?
Loaded new LL data into demo dpx - function works. Added new shapefiles that are not WGS84 originally - stopped working. Changed datum projection in TERR script to NAD27, still didn't work. Left the datum NAD27 and switched back to shapefile with WGS84 projection and it worked again.

Hi, John - In the Spotfire Map Visualization itself, there are 3 locations where the coordinate reference system (CRS) needs to be specified,
1) the overall projection of the Map Chart, under Map Chart Properties - Appearance
2) and 3), under each layer's settings, under Data
I would ensure that both the points and shapefile use the same CRS before sending to the "Points in Polygons" data function.
If the points and shapefile use different CRSs, we do provide some utility TERR data functions that can be used to transform the CRS for either shapefiles or markers, here is the link to these data functions on the Location Analytics wiki page.
