I am looking for a way in QGIS (1.8.0) to visualise data, which is related to an area (polygon on a shape file). There are no x-y-coordinates with the data, just the info of the belonging area, means at an arbitrary position inside the area.
Example: Samples x1,x2 and x3 are located in area a1, y1 to y5 in area a2.
As the samples have certain properties on which I intend to do queries on, distinct locations seems somehow necessary (e.g. sample x1 and x3 have a certain property and therefore should be shown/highlighted ).
I initially thought of assigning each sample some random coordinates from inside the areas, but what a hassle..
So, how to approach that??
