Feature request: choose between distance and time in x-axis of profile

Profile:

On the y-axis it's possible to choose between elevation and speed but it would be possible to add the ability to choose between distance and time on the x-axis.

It's quite some effort but doable. Why would you want to do it? What's the value of having the elevation or speed over time profile?

Interresting feature request...

x-axis by air-to-air distance is, let's say... 'non-linear'...
x-axis by time may be useful for photo taggers to sort their pictures based on a linear time based profile.

Sorry for the late answer.

In a graph, with the distance in the x-as, data gets distorted because the lower the speed (the lower the increase in distance) the more that data gets shrunk compared to the parts where you moved with a higher speed.

For example: you walk one hour at 10km/h, then you rest (stay at the same place) for one hour and then again you walk for one hour at 10km/h.

In a graph with the distance in the x-as the part you rested for one hour won't be visible because the distance didn't increase.

In a graph with the time in the x-as it is clear that one third of the time you stayed at the same place.

ps: thx for the superb track editor !

Ok, got it. Implementing time as x-axis has two difficulties

• good usability, precise naming on the surface (currently there is just 'Show profile', I'd like to find better names that horizontal and vertical axis when extending this)
  
• making backing structures more flexible while keeping the optimizations alive that make the profile view work for huge tracks
  

I could need some help there.

I think I forgot to state that this feature has been implemented a long time ago.
