Magics is the latest generation of the ECMWF's meteorological plotting software and can be either
accessed directly through its Python or Fortran interfaces or by using Metview.
Features:
- supports plotting of contours, wind fields, observations, satellite images, symbols, text, axis and graphs (including boxplots)
- can plot GRIB 1 and 2 coded data, gaussian grid, regularly spaced grid and fitted data
Limitations:
- development stage: **Alpha**,
Installation
------------
The package is installed from PyPI with::
$ pip install Magics
System dependencies
~~~~~~~~~~~~~~~~~~~
The python module depends on the ECMWF *Magics* library
that must be installed on the system and accessible as a shared library.
Some Linux distributions ship a binary version that may be installed with the standard package manager.
On Ubuntu 18.04 use the command::
$ sudo apt-get install libmagplus3v5
As an alternative you may install the official source distribution
by following the instructions at
https://software.ecmwf.int/magics/Installation+Guide
Note that *Magics* support for the Windows operating system is experimental.
You may run a simple selfcheck command to ensure that your system is set up correctly::
$ python -m Magics selfcheck
Found: Magics '4.0.0'.
Your system is ready.
Usage
-----
First, you need a well-formed GRIB file, if you don't have one at hand you can download our
a 2m temperature grib file::
$ wget http://download.ecmwf.int/test-data/magics/2m_temperature.grib
You may try out the high level API in a python interpreter::
from Magics import macro as magics
name = 'magics'
#Setting of the output file name
output = magics.output(output_formats = ['png'],
output_name_first_page_number = "off",
output_name = "magics")
#Import the data
data = magics.mgrib(grib_input_file_name = "2m_temperature.grib", )
#Apply an automatic styling
contour = magics.mcont( contour_automatic_setting = "ecmwf", )
coast = magics.mcoast()
magics.plot(output, data, contour, coast)
Running the test program will create a png named magics.png
