I added pie charts via text-file to my map.
When printing the map they get lost. Does anyone know how to print them?
QGIS also seems to delet some charts, when there are to many at one place. Does anyone have a solution for that?
I had similar problem and I didn't found perfect solution.
However, I made pie charts in Quantum GIS, then I export pie charts to SVG-file. Then I finalize my map with Inkscape: manually drag pie's to better place. Result:
I have also other solution in my mind. I'd like to add these pie chart "movements" to my Spatialite table. Then I can have view in Spatialite to draw pie charts in best places.
I also suggest that automatic re-placement of pie's should be in QGIS. But this request has been postpone to future releases (after 2.x).
