I'm using QGIS 2.8.2 and want to define the position of diagrams with x and y coordinates.
The same thing works with the labels, but when I define coordinates for the diagrams they just disappear. I've tried different ways of coordinates but everytime they disappear. I think there is a problem with the Coordinate Reference System. I had to use WSG 84 EPSG:3857 and EPSG:4326 because otherwise my map is stretched.
I'm searching the web and the documentation for hours but i can't solve the problem, i am still a very beginner. Has anyone an idea to fix my problem?
