oceanspy.plot.TS_diagram

oceanspy.plot.TS_diagram(od, Tlim=None, Slim=None, dens=None, meanAxes=None, colorName=None, plotFreez=True, ax=None, cmap_kwargs=None, contour_kwargs=None, clabel_kwargs=None, cutout_kwargs=None, **kwargs)[source]

Plot temperature-salinity diagram.

Parameters:

od: OceanDataset: oceandataset used to plot.
Tlim: array_like with 2 elements: Temperature limits on the y axis. If None, uses min and max values.
Slim: array_like with 2 elements: Salinity limits on the x axis. If None, uses min and max values.
dens: xarray.DataArray: DataArray with densities used for isopycnals. Must have coordinates (Temp, S). In None, dens is inferred from Temp and S.
meanAxes: 1D array_like, str, or None: List of axes over which to apply weighted mean. If None, don’t average.
colorName: str, None: Name of the variable to use to color (e.g., Temp). If None, uses plot insted of scatter (much faster)
plotFreez: bool: If True, plot freezing line in blue.
ax: matplotlib.pyplot.axes: If None, uses the current axis.
cmap_kwargs: dict: Keyword arguments for the colormap (same used by xarray)
contour_kwargs: dict: Keyword arguments for matplotlib.pytplot.contour() (isopycnals)
clabel_kwargs: dict: Keyword arguments for matplotlib.pytplot.clabel() (isopycnals)
cutout_kwargs: dict: Keyword arguments for oceanspy.subsample.cutout()
**kwargs:: If colorName is None: Kewyword arguments for matplotlib.pytplot.plot() Otherwise, kewyword arguments for matplotlib.pytplot.scatter()

Returns:

ax: matplotlib.pyplot.axes: Axes object.
