Step-by-step guide
The behaviour of Text Plotting icons (mtext() in Macro) changed slighly in Metview 5 - these objects can have Text Mode set to either 'title' or 'positional', the former meaning that the text will appear above the plot, the latter meaning that the user specifies the on-screen coordinates of where the text will appear. In Metview 4, if you created a 'positional' text (in Macro, text_mode:'positional'), it would override the default title. This was changed in Metview 5 so that a positional text would not override the default title
This means that a positional text now appears in addition to the normal title. To remove the default title, you can create an empty title and add it to the plot() command:
empty_title = mtext(text_line_1 : ' ') plot(...., empty_title)
We have sometimes seen positional titles being placed in the default title position above the plot. If this is the case, then it could be enough to change that one from 'positional' to 'title', and then it would override the default title with no need to create an empty one.
