Marker tooltip with negative elevation

[mttucl]

When displaying bathymetry data, the marker tooltip line is shown above the path with the tip outside the map. This only happens if all data is negative. If there is another path with positive elevation data, it will only happen if I display the bathymetry data first for the first time after loading the page. Once I check the other path, it will display the bathymetry data tooltip correctly.

Sorry, I don't have a working example but you can try the geojson demo example with attachment (change txt to geojson).

Hi @mttucl,

If you're interested in seeing it resolved, please check it out and pitch a PR.

I would say that the problem is related to yMax calculation (I haven't checked in detail):

which also depends on yCoordMax variable:
