Y-axis scaling issue when displaying grade profile

<< < (2/2)

guney:
You know what? I just came across another example that goes against what we just discussed. Take a look at this grade plot:



In this screenshot, the max value on the Y axis is, again, 10%. (It seems to be cut off due to window size, but no amount of vertical resizing expands the Y axis range in that direction. Only the labeling changes.) However, the min value on the Y axis is somewhere around 19%. In fact, this graph successfully accommodates the lower extreme of its dataset. Only the upper extreme gets cut off.

This example makes it look to me like an on-the-fly value range computation is being attempted but (at least for the max end in this example, and for both ends in the previous one) is failing. At the very least, it's not a hard-coded 10% to -10% range.

I'm not trying to prove a point. Just wanted to prevent a potential misconclusion.

Krein:
Gotcha.  Just got back from a trip, but will look at this ASAP.

The way the profiler computes grade is a little funny. There's some smoothing in there, so that may be part of what's throwing it off.

Thanks for the post.

Krein:
Hi,

The latest version clears up this issue.  Thanks much for pointing it out.

The min/max was being set by the min/max of all loaded files, but it was their average uphill and downhill grade.  Thus the limited but moveable range.

That was definitely a bug.

Now you'll get the full range for the currently profiled track.  There's a tiny bit of smoothing right now.  In the next version we'll have buttons to increase/decrease smoothing which should help quite a bit for grade plots.

Krein:
Just wanted to add that this bug with the grade range was introduced in the last few versions -- older versions were doing it correctly, but when we upgraded the profiler to do HR/Cad/Power it got fouled up.

guney:
Thanks! And I'm glad to be of help.
