VIRB Edit Elevation Overlay

Elevation graph plotted against time instead of distance???

Hi Eilidh,

I encountered the same problem, I always thought the elevations graphs were off in a way but not very clear, untill last trip we had some pauses, it became clear that the elevation graph is plotted against time instead of against distance what I expected.

To developer, can this be changed? I would like to have elevation and other graphs plotted against distance by default as it is in basecamp.

To illustrate the issue please have a look here.

This could potentially be changed, but currently all the widgets are based on time. It's actually a fair amount of work to change this, so to be perfectly honest, I am not sure if we'll be able to make that change anytime soon.

I'm going to go ahead and say that you should rethink this. Elevation profiles with time as the x axis are pointless, and elevation profiles are one of a very select few overlays that are of primary interest to cyclists.

As a software engineer, let me make an implementation suggestion for you. As you say, all of your widgets are based on time. Why not make a global change to make all of them based on a function of time. So instead of x=time, x=f(t). For every widget except elevation profile that function can simply return the time, so f(t)=t and there is no change. But, for the elevation profile the function x=f(t) looks up the distance at the time t and returns the distance. This way all widgets continue to operate consistently, the behavior remains unchanged for all widgets except elevation profile, and you now have converted a useless widget into an extremely useful one.

Again, think it through. Elevation profile with time as the x-axis is deceptive and inconsistent with every elevation profile cyclists are used to. I would simply call it a bug in its current state and you'd be better off not offering the elevation profile at all. You really should consider a fix for this. Other software, like the Cyclops Virtual Trainer overlays manage to graph some things by time and others by distance. You should do the same.

Would I be correct in assuming that this is a function of the entire Garmin product line? I have an automotive Garmin GPS unit and note that the elevation that I have continually displayed generally is a couple of seconds behind my actual location. After I have crested a grade and started down, the unit says I am still going up.
