I'm working with Qgis on a project and I have a small problem. I have to do some demographic research and therefore I have a .shp file from a given country with 10 districts for example.
Now, I know how to insert pie charts but the problem is that I only want to insert one pie chart for one district because this area is of importance to me for example.
So I added a column in the attribute table with data for the district that I want to display and left all the other values 'NULL'.
However, if I insert pie charts, they appear for all the districts, even though I've not inserted any values in the attribute table for the other 9 districts that are of no interest to me.
Does anybody know how I can only display one pie chart for 1 feature of the polygon instead of having 1 good pie chart and 9 empty on the map?
