Colouring text background and labels

[gkafk]

Hi,

Is there any way of colouring the background of text region?

A text_box_blanking but with colour or transparency?

Also, is there any way of making contour lines cut around label?

like that?

thanks George

Hi George,

Good questions! To go beyond the simple white background that you get with text_box_blanking='on' you need to use the Annotation View, described a bit here: https://confluence.ecmwf.int/display/METV/Layout+in+Metview

Here is some Python code that uses it the way you want:

text = mv.mtext(
    text_lines          = ["Hello world", "How are you?"],
    text_colour         = "black",
    text_font_size      = 0.5,
    text_mode           = "positional",
    text_justification  = "left"
    )

gview = mv.geoview()

geo_page = mv.plot_page(view = gview)

annotation_view = mv.annotationview(
    #subpage_background_colour = "peach"
    subpage_background_colour = "RGBA(1, 0.5, 0.5, 0.5)"
    )

text_page = mv.plot_page(
    top    = 40, # % of main page from top-left
    bottom = 50,
    left   = 30,
    right  = 55,
    view   = annotation_view
    )

dw = mv.plot_superpage(pages = [geo_page,text_page])

mv.plot(dw[0], data, dw[1], text)

Unfortunately we do not support the gaps in isolines required for your second question, but blanking of labels is on, as long as you don't turn off contour_label_blanking.

I hope this helps a little!

Thanks Iain.

I will try it.
