Version 1.9.0

Released on github and pypi (pip install metview). Installed at ECMWF as part of metview/5.14.0

  • the plot functions now automatically plot inline if running inside a Jupyter notebook
    • it is no longer necessary to call setoutput('jupyter')
    • call setoutput('screen') to force the interactive plot window to appear
  • inline plots in Jupyter notebooks will be automatically trimmed of surrounding whitespace if pillow is installed
  • new functions to build popup dialogs and read in user input. Available via the newly added ui module.
    • ui.dialog()
    • ui.any()
    • ui.colour()
    • ui.icon()
    • ui.option_menu()
    • ui.slider()
    • ui.toggle()
  • added high-level plotting functions to be used with Datasets or in Jupyter notebooks
    • plot_maps()
    • plot_diff_maps()
    • plot_xs()
    • plot_rmse()
  • new object Track to represent a storm track
  • new function make_geoview() to generate a geoview object with predefined settings
  • new interface for Datasets
  • added new keyword argument called check_local to gallery.load_dataset(). If it is True and the data file exists locally it will not be downloaded.
  • fixed issue when describe() crashed when called with a paramId

Version 1.8.1

Released on github and pypi (pip install metview). Installed at ECMWF as part of metview/5.13.2

  • fixed case where map_area_gallery() crashed
  • fixed case where map_style_gallery() crashed
  • fixed issue where plot_maps() could not plot wind data
  • fixed issue where a style could not be updated when verb argument is specified

Version 1.8.0

Released on github and pypi (pip install metview). Installed at ECMWF as part of metview/5.13.0

  • new functions/methods on Fieldset to give an overview of contents:
  • new GRIB filtering function, select(), offers different filtering options from read() and is faster
    • see Jupyter notebook example
    • new shorthand way to select parameters from Fieldsets, e.g.
      • g = fs["t"]

      • g = fs["t500"]

      • g = fs["t500hPa"]

      • see docs
  • the Fieldset constructor can now take a list of paths to GRIB files or a wildcard, e.g.
    • a = mv.Fieldset(path=["/path1/to/data1.grib", "relpath/data2.grib"])
      a = mv.Fieldset(path="data/*.grib")
  • the result of a call to mcont() etc can now be modified, e.g.
    c = mv.mcont() ; c["contour_line_colour"] = "green" ; mv.plot(data, c)
    gv.update({"MAP_COASTLINE_land_SHADE_COLOUR": "green"}, sub="COASTlines")
  • improved the output of print(Fieldset):
    "Fieldset (6 fields)"

Version 1.7.2

Released on github and pypi (pip install metview). Installed at ECMWF as part of metview/5.12.0

  • documentation now available on readthedocs!
  • improvements in plotting into Jupyter notebooks so that the plot() command works in a loop or an 'if' statement
  • new parameter when calling setoutput to force the plot() command to return an Image rather than a widget - this allows plots to be embedded in the notebook when you save it, e.g.


    • Code Block
      mv.setoutput('jupyter', plot_widget=False)


  • when built with Metview 5.12, you can add a new parameter to setoutput() to scale the fonts, e.g.


    • Code Block
      mv.setoutput('jupyter', output_width=800, output_font_scale=1.5)


Version 1.7.1

Released on github and pypi (pip install metview). Installed at ECMWF as part of metview/5.11.1

  • added 'play' button to the animation widget in Jupyter using mv.plot(...., animate=True)

Image Added

Version 1.7.0

Released on github and pypi (pip install metview). Installed at ECMWF as part of metview/5.11.0

  • added animate=True argument to plot() command for animated plots in Jupyter notebooks
  • allowed cfgrib backend keyword arguments to be passed to Fieldset.to_dataset(), e.g.
    • my_fieldset.to_dataset(squeeze=False, read_keys=["experimentVersionNumber"])
  • Fieldset out-of-range indexing now raises an IndexError
  • Fieldset merge() function now allows a single Fieldset as argument

The animation control provides a simple slider to control which step of an animation is displayed:
