Now you can ability to show elevation diagram for KML and GPX files
Just in paths for your file layer use KML (internal parser) or GPX (internal parser).
On tab “Elevation” set diagram position. All of other values you can set by default.
When you move on diagram – you can see marker on map, and if you move on path – you can see it on diagram.
You can select range on diagram and path will be zoomed.
PS some styles (for example Red) is not configured. It will be in future.
PPS due to link to last release was broken, my extension temporary unpublished in JED. Just wait a little. But updates you can get by Extension Manager in admin panel.
