- 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 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. - automatic titles: whereas MAGICS 6 used to try to combine titles from different data onto a single line, Magics++ does not. So if a plot is the result of overlaying two GRIB fields, the automatic title will have two lines. The features mentioned below can be used to construct a semi-automatic title if this is not the desired behaviour.
- 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
- where Metview 3 used
- convert the date and time information according to a format string defined in C++ std::strftime (http://www.cplusplus.com/reference/ctime/strftime/)
- automatically add GRIB meta-data to a 'semi-automatic' plot title using GRIB_API keys. For instances:
- In Macro,
ptextis replaced bymtext.
