[Qgis-user] Converting or rendering GPS track points as line but preserving point data

[Nathanael Boehm]

I promise not to spam the mailing list, but I do have another question I'm
hoping someone can help with.

In other GPS software like ExpertGPS or the online GPSVisualizer you can
style a GPS track based on track point attributes like elevation or
timestamp etc.

However when you import GPS or GPX data into QGIS (either as a new vector
layer or using the vector tools and GPS plugin) it treats the track points
and track line as separate layers … and the line is pretty useless except
for visually connecting the dots, but it has no data associated with it.

This is a GPS track in QGIS with a graduated classified style applied on
the elevation "ele" attribute of the track points:

I would like to render this as a line but still have access to all 250+
vertices in order to apply styling like I have above (but as a line instead
of 250+ individual points as it's kind of ugly)

Is it possible? I've tried Point2One with no success. All I've managed so
far is to add the geometry columns to the track points layer, but that
doesn't help with creating the polyline.
