Inspect the GRIB icon (right-click on it and choose examine) to see the type of input data this View requires - it should be gridded data (rather than spherical harmonics) and it should contain fields at multiple vertical levels.
If the data is given in model levels then a Logarithm of Surface Pressure field must be provided too should the orography and the vertical axis of the plot in pressure levels rather than model levels is required when visualising the output.
To customise the transect line (coordinates along which the cross-section is calculated), do the following:
