Parameters Title, Vertical Axis and Horizontal Axis are no longer available in the user interface (Metview 4 compliant: they are not part of the data computation). If the icon action is visualise then default values for these parameters will be used. To customise the output title and axes, use icons Text Plotting and Cartesian View, respectively. Note that you might have to delete the existing Spectra icon from your System/Defaults folder if you cannot edit the new icon.
