I am trying to get elevation graph with the Terrain profile tool on my GPS data and can't get it to work. I have GPX file from a drive. I got this imported in QGIS. I have elevation data for each point but when using the Terrain profile tool over this GPX file or the derived shape file, all I get is a flat graph.
I have also tried converting my points shp to line shp file using the point to path in the toolbox but when doing so, I am loosing the elevation data
Anybody can describe the steps to use effectively the point elevation data to create a profile graph?

Steps with the Profile Tool :
Open both the track and track_points in QGIS.
Open the Profile Tool plugin.
Select the point layer in the Layers Panel and click on Add Layer in the Profile Tool.
Choose the elevation field.
Select the track (line) layer in the Layers Panel.
Select selected layer in the Profile Tool in Options > Selection.
Wait and the plot will be created automatically.
The Profile Tool is great to use when you want to use a DEM as reference to trace profiles of polylines but with GPX files I always prefer to use qProf instead, at least on my computer the performances of the Profile Tool with big GPX files are really poor and QGIS crashes (but maybe I don't configure it right).
