Metview's Map View has been replaced by Geo View, allowing access to the new projections of Metview 4. Note that there is now a new parameter with which you must specify whether you wish a global or non-global area (set Map Area Definition = Corners for a non-global area). Legacy Map View icons will still work.

...

Metview 4 completely revised its handling of Text, Annotation and Legend Plotting. The mains differences are:

• legend: the Text Plotting icon no longer has any legend parameters - these are all now contained in the Legend icon.
• font size: Metview 3 (using MAGICS 6) automatically adjusted text font size in order to fit inside its containing box. A common technique was to define a large text size and let Metview scale it down automatically. Metview 4 (using Magics++) does not do this; it will use exactly the font size specified. Note that instead of Text Reference Character Height, Metview now uses Text Font Size.
• user titles: The way to specify user text in a title has changed a little. Metview 3 contained options to specify The way to specify user text in a title has changed a little. Metview 3 contained options to specify whether a title contained automatic text, user text or both; Metview 4 instead has a default title line which is "<magics_title/>". Any text line with this string will have the automatic title; lines without it will not.
• Magics++ also has features, documented here, to:
  • automatically add GRIB meta-data to a 'semi-automatic' plot title using GRIB_API keys. For instances:
    • where Metview 3 used !PARAM!  Metview 4 would use <grib_info key='name'/>
    • provide two extra keys: base-date and valid-date
  • convert the date and time information according to a format string defined in C++ std::strftime (http://www.cplusplus.com/reference/ctime/strftime/)
  Another commonly-encountered change is that instead of Text Reference Character Height, Metview now has Text Font Size.

• In Macro, ptext is replaced by mtext.

• The Metview-Vis5D interface has been replaced with an interface to the VAPOR software; see 3D visualisation with VAPORNative plotting support for satellite projection images - the workaround is to use the Reprojection module to reproject the data onto a regular lat/lon grid, then plot this onto a Geo View using the Geos projection. This is currently limited to having its centre at zero degrees longitude.VAPOR software; see 3D visualisation with VAPOR
• Hovmoeller, cross section, zonal/meridional mean and vertical profile plots only generate a plot for the first set of data supplied. In Metview 3 for instance, you could supply a time series of vertical level data to the Cross Section module and receive one plot per time step; now, only the first time step will be plotted. The workaround is to write some Macro code to loop through the steps/parameters/etc and generate one plot at a time.
• The Satellite View is not available - see above- the Geographical View allows the selection of the Geos projection, which simulates the view from a satellite; this is currently restricted to a sub-satellite point of zero degrees longitude, but this restriction may be lifted
