I had done that already several times the past couple of days, but to no avail. At this moment however, the ribbon seems to correspond much better somehow.

@Suty, thanks for the quick reply, it already seems to be fixed indeed!

For our current location offshore Poland, in Basic most individual forecasts show the wind increasing above 16 knots a couple of hours before midnight. This is also the case with the comparison function. Using Wind, all show the increase only after midnight however.

Good evening. Is there a developer who has been reading up on this?

Obviously it is past the forecast duration, but the problem occurs within the forecast duration. I don't remember from the past that long routes were a problem.

As I posted a link to my route, I thought it was obvious that it has 30+ waypoints. Anyway, here you go:

I can export it, but I can not upload it here. The single great circle voyage from your example plots fine here as well. It is the voyage with 30+ waypoints that gives issues. Have you been able to convert above code into a gpx-file?

I do not seem to have the privileges to upload, but the code in the gpx-file is blow (as it doesn't display code properly, I changed < for [. If you change that back in Notepad and save it as gpx-file, hopefully it works).

What about the link with the route in my first post?

That example plots well over here as well, but is a short track while the differences are not that much.

Yes, it's the ECMWF model indeed.

Do the programmer also read these posts?
