I'm trying to draw a pie chart on QGIS, over a polygon layer. This pie chart should include data from 6 fields in the attribute table. These fields contain the percentage of several categories of data and all of them sum up to 100% (I've checked it personally). However, the diagrams option in...

I am working with polyline shapefile. I need to add point data at every intersection of polyline/polygon which was no problem->simple intersection. Problem is, points were not added to the ends (start/end) of each polyline. I am working on a basic license and am very limited to what tools are...
