**Visualization on a map with psyplot**
=========================================

This tool wraps the functionality of ``psyplot.plot.mapplot``.


.. class:: infomark

        The wrappers aims at providing the same functionality as ``psyplot.plot.mapplot`` but it has some limitations.
        The input file must be in netCDF format and must contain 2D arrays with geographical coordinatates
        (latitudes, longitudes) given in degrees.
        TODO: Fill in help.

**What it does**
----------------

This tools creates an image (png format) corresponding to the visualization on a geographical map of a variable extracted from a
netCDF file (input file). By default, the projection is ``PlateCarree`` and colormap is ``jet``. These settings can be changed in *Advanced settings*.


**Usage**

::

  usage: psymap_simple.py [-h] [--proj PROJ] [--cmap CMAP] [--output OUTPUT] [-v] input varname


Positional arguments:
~~~~~~~~~~~~~~~~~~~~~

- **input**:            input filename with geographical coordinates (netCDF format)
- **varname**:          Specify which variable to plot (case sensitive)

Optional arguments:
~~~~~~~~~~~~~~~~~~~~~

  -h, --help       show this help message and exit
  --proj PROJ      Specify the projection on which we draw
  --cmap CMAP      Specify which colormap to use for plotting
  --output OUTPUT  output filename to store resulting image (png format)
  -v, --verbose    switch on verbose mode

It uses psy-maps, a python package to generate plots. More information about
psyplot and psy-maps can be found at https://psyplot.readthedocs.io/projects/psy-maps/en/latest/
