marine_qc.visualization package

Marine Quality Control plotting package.

marine_qc.visualization.plot_latitude_longitude(lat, lon, qc_outcomes, xlim=None, ylim=None, marker_size=None, add_coastlines=False, filename=None)

Plot a graph of points showing the latitude and the longitude of a set of observations coloured according to flagged outcomes.

Parameters:

  • lat (numpy.ndarray) – Array of latitude values in degrees.

  • lon (numpy.ndarray) – Array of longitude values in degrees.

  • qc_outcomes (numpy.ndarray) – Array containing the QC outcomes, with 0 meaning pass and non-zero entries indicating failure.

  • xlim (tuple of float and float, optional) – Limits of the current x axis. If None, set to (-180.0, 180.0).

  • ylim (tuple of float and float, optional) – Limits of the current y axis. If None, set to (-90.0, 90.0).

  • marker_size (int, optional) – Marker size in points. If None, it is set to 1.

  • add_coastlines (bool) – If True, add coastlines on PlateCarree projection.

  • filename (str, optional) – Filename to save the figure to. If None, the figure is not saved but shown.

Return type:

Figure

Returns:

Figure – The main figure object created by plt.subplots().

marine_qc.visualization.plot_latitude_variable(lat, value, qc_outcomes, xlim=None, ylim=None, marker_size=None, add_coastlines=False, filename=None)

Plot a graph of points showing the latitude and the value of a set of observations coloured according to flagged outcomes.

Parameters:

  • lat (numpy.ndarray) – Array of latitude values in degrees.

  • value (numpy.ndarray) – Array of observed values for the variable.

  • qc_outcomes (numpy.ndarray) – Array containing the QC outcomes, with 0 meaning pass and non-zero entries indicating failure.

  • xlim (tuple of float and float, optional) – Limits of the current x axis.

  • ylim (tuple of float and float, optional) – Limits of the current y axis. If None, set to (-90.0, 90.0).

  • marker_size (int, optional) – Marker size in points. If None, it is set to 1.

  • add_coastlines (bool) – If True, add coastlines on PlateCarree projection.

  • filename (str, optional) – Filename to save the figure to. If None, the figure is not saved but shown.

Return type:

Figure

Returns:

Figure – The main figure object created by plt.subplots().

  • qc_outcomes (numpy.ndarray) – Array containing the QC outcomes, with 0 meaning pass and non-zero entries indicating failure.

  • xlim (tuple of float and float, optional) – Limits of the current x axis. If None, set to (-180.0, 180.0).

  • ylim (tuple of float and float, optional) – Limits of the current y axis.

  • marker_size (int, optional) – Marker size in points. If None, it is set to 1.

  • add_coastlines (bool) – If True, add coastlines on PlateCarree projection.

  • filename (str, optional) – Filename to save the figure to. If None, the figure is not saved but shown.
