I have installed and followed the process to produce an elevation profile from the Route Profile plug-in in QGIS, but for some reason I am getting no profile to appear.
The grids are from OS Terrain50 and the route is a polyline shapefile. The tool version is 3.7.0 and I am using QGIS Lyon 2.12.0 on a Mac (El Capitan).
I have attached a screenshot of what is appearing.
I cannot see what I am doing wrong.
