I'm using QGIS 2.18.3 (Las Palmas). I have created pie charts for a layer in QGIS and in order to be able to move the pie charts around i processed the centroids of my polygons. By moving the (Centroid) points I am now able to move the pie charts around.
I still have some overlapping in my charts, so i'm looking into creating leading lines, so I can allocate the pie chart to its polygon. I have looked into previous questions here (for example How to create dynamic leader lines? or Creating leader lines for moved labels) but I dont seem to be able to use it for the charts.
How can I create a leading line for a pie chart?
