I'm using the Map Chart of Spotfire 6.5 to visualize components of a semiconductor chip. The feature layer is created using a WKB column in the information link. It works fine to show all components, but even if I switch off Auto Zoom, I can't zoom in to see smaller components individually. Also, the Scale feature doesn't work. Any idea what's wrong? Is it maybe connected to not using a Coordinate Reference System? But how can I use that if I just have a nanometer scale rectangular coordinate system.
