Pace wrong in plots

Open marcelmindemann opened this issue 1 year ago • 1 comments

Describe the bug I think the plotting of my pace against time/distance is broken. I did a run yesterday where my average pacr was around 7 min/km. This is consistent with the breakdown into 1km intervals.

However the graphs show my pace averaging around 8.6 min/km. That's constantly too high when compared with the interval screen.

I have no good explanation for this behavior. Two options:

  • the pace computation is broken in the charts
  • or the rendering of the chart is broken (code is ancient ;) )

I'm not sure if this is what I'm dealing with or not, so before making a new ticket, I'll describe my issue and let you tell me whether it belongs here or in its own issue:

I recently started using OT for my run/walk intervals (had been using it for a while for my cycling), and if I stop for any period of time to rest, adjust my knee brace, etc., it shows up as a huge spike in my graph. This results in my Pace plotting having a scale up to 600 min/mi, which makes reading that data on the graph impossible.

@SlidingHorn that sounds like a different problem. Can you open a new issue? And what device are using as it feels like as.if the problem might the GPS device. OpenTracks nowadays just stores the recorded data (ie. no further filtering of speed data).

@marcelmindemann just had some time to look I to this. The problem are the labels on the y-axis. It should start with a 0 for pace/speed. The actual plot seems correct when taking this i to account. Labels should be 0, 5, 10, etc.

Don't know exactly why this looks this way for you.

So, this might be relevant: https://github.com/OpenTracksApp/OpenTracks/issues/795 BUT I didn't see a relevant change in the commits (yet).

@marcelmindemann Can you send me an example track to [email protected]? I cannot reproduce the problem locally. And does this problem only occur with pace or also with speed?

Please re-open if this is still an issue.
