Missing axes in transects when ensembles are used as input data

### Describe the bug

Transect plots in ensemble mode removes the axes from the plots so the user has no idea of height or positioning.

### How to reproduce

Steps to reproduce the behaviour:

1. Select plevel transect with ensemble data

### Expected behaviour

Axes are provided.

No file, test, or entry point is named. First reproduce the issue by selecting a plevel transect with ensemble data, then trace the transect plotting path and compare it with non-ensemble plots. Done means the ensemble transect displays axes that communicate height and positioning.
