My title which has <b>bold</b>, <u>underlined</u> and <font color='rose'>coloured</font> text |
Some Metview users have used coloured text in the title as an alternative legend.
If you are writing a macro, then you can use all of the string manipulation capabilities to construct the title. Type the following macro code, or try the one in the solutions folder. It calls the grib_get functions to retrieve meta-data from the GRIB header, then constructs a title using it.

rh = read("relative_humidity.grib")
field_name = grib_get_string(rh[1], 'name')
field_valid_date = grib_get_string(rh[1], 'validityDate')
field_level = grib_get_double(rh[1], 'level')
title_text = field_name & ' ' & field_valid_date & ' at level ' & field_level
title = mtext(text_line_1: title_text)
plot(rh, title) |
This is fine for a single field, but notice that if you move between the two fields in the relative_humidity data, there are two different vertical levels - but we only have one title, and it was constructed using the meta-data from the first field.
