Functions

epygram.fields.V1DField.plotprofiles(profiles, over=(None, None), labels=None, fidkey=None, Ycoordinate=None, unit='SI', title=None, logscale=False, ema=False, zoom=None, figsize=(6.0, 9.0), rcparams=None, colors=None, legend_kwargs=None)[source]

To plot a series of profiles. Returns a tuple of matplotlib (Figure, ax).

Parameters:
  • profiles – a epygram.base.FieldSet of epygram.fields.V1DField, or a single epygram.fields.V1DField. All profiles are supposed to have the same unit, and the same vertical coordinate.
  • over – any existing figure and/or ax to be used for the plot, given as a tuple (fig, ax), with None for missing objects. fig is the frame of the matplotlib figure, containing eventually several subplots (axes); ax is the matplotlib axes on which the drawing is done. When given (is not None), these objects must be coherent, e.g. ax being one of the fig axes.
  • labels – a list of labels for the profiles (same length and same order).
  • fidkey – key of fid for labelling the curve with fid[fidkey]; if None, labels with raw fid.
  • Ycoordinate – label for the Y coordinate.
  • unit – label for X coordinate.
  • title – title for the plot.
  • logscale – to set Y logarithmic scale
  • ema – to make emagram-like plots of Temperature
  • zoom

    a dict containing optional limits to zoom on the plot.

    Syntax: e.g. {‘ymax’:500, …}.

  • figsize – figure sizes in inches, e.g. (5, 8.5). If None, get the default figsize in config.plotsizes.
  • rcparams

    list of (*args, **kwargs) to be passed to pyplot.rc() defaults to [((‘font’,), dict(family=’serif’)),

    ((‘figure’,), dict(autolayout=True))]
  • colors – list of matplotlib colors on which to iterate to plot each profile. Cyclic (with varying linestyle) if shorter than the number of profiles.
  • legend_kwargs – kwargs to be passed to matplotlib’s legend()
epygram.fields.V1DField.plotverticalhovmoller(profile, over=(None, None), fidkey=None, Ycoordinate=None, title=None, logscale=False, zoom=None, colorbar='vertical', graphicmode='colorshades', minmax=None, levelsnumber=21, center_cmap_on_0=False, colormap='jet', minmax_in_title=True, contourcolor='k', contourwidth=1, contourlabel=True, datefmt=None, showgrid=True, figsize=(6.0, 9.0), rcparams=None)[source]

Makes a simple vertical Hovmöller plot of the field.

Parameters:
  • profile – being a epygram.fields.V1DField
  • over – any existing figure and/or ax to be used for the plot, given as a tuple (fig, ax), with None for missing objects. fig is the frame of the matplotlib figure, containing eventually several subplots (axes); ax is the matplotlib axes on which the drawing is done. When given (is not None), these objects must be coherent, i.e. ax being one of the fig axes.
  • fidkey – type of fid for entitling the plot with fid[fidkey], if title is None; if None, labels with raw fid.
  • Ycoordinate – label for the Y coordinate.
  • title – title for the plot.
  • logscale – to set Y logarithmic scale
  • zoom

    a dict containing optional limits to zoom on the plot.

    Syntax: e.g. {‘ymax’:500, …}.

  • colorbar – if False, hide colorbar the plot; else, befines the colorbar orientation, among (‘horizontal’, ‘vertical’). Defaults to ‘vertical’.
  • graphicmode – among (‘colorshades’, ‘contourlines’).
  • minmax

    defines the min and max values for the plot colorbar.

    Syntax: [min, max]. [0.0, max] also works. Default is min/max of the field.

  • levelsnumber – number of levels for contours and colorbar.
  • center_cmap_on_0 – aligns the colormap center on the value 0.
  • colormap – name of the matplotlib colormap to use.
  • minmax_in_title – if True and minmax is not None, adds min and max values in title
  • contourcolor – color or colormap to be used for ‘contourlines’ graphicmode. It can be either a legal html color name, or a colormap name.
  • contourwidth – width of contours for ‘contourlines’ graphicmode.
  • contourlabel – displays labels on contours.
  • datefmt – date format to use, e.g. “%Y-%m-%d %H:%M:%S %Z”
  • showgrid – True/False to show grid or not
  • figsize – figure sizes in inches, e.g. (5, 8.5). If None, get the default figsize in config.plotsizes.
  • rcparams – list of (*args, **kwargs) to be passed to pyplot.rc() defaults to [((‘font’,), dict(family=’serif’)),]

Warning: requires matplotlib.

epygram.fields.V1DField.plotanimation(profile, title='__auto__', repeat=False, interval=1000, **kwargs)[source]

To plot a time-dependent profile as an animation. Returns a matplotlib.animation.FuncAnimation.

Parameters:
  • profile – the epygram.fields.V1DField to plot.
  • title – title for the plot. ‘__auto__’ (default) will print the current validity of the time frame.
  • repeat – to repeat animation
  • interval – number of milliseconds between two validities

Other kwargs passed to plotprofiles().
