is there a way in Stat Plant Plus to avoid the map regions with NO DATA or when the value is equal to zero, from being graphed? The thing is that I have maps of municipalities (a bunch of them) and in their background there is a map of the state to where the municipality belongs. I merged them using QGIS 1.8.0. The issue is that I want the state to be displayed on the background but not being graphed (because I dont have information to put there) because in the graph each state appears as zero and is very misleading, it also looks funny.
Please let me know.
