xarray.Dataset.hyoga.plot.scale_bar#

Dataset.hyoga.plot.scale_bar(ax=None, label=None, loc='lower right', size=None, **kwargs)#

Add a horizontal bar with a text label showing map scale.

Parameters:

  • ax (matplotlib.axes.Axes (or a subclass), optional) – Matplotlib axes used for plotting. Default to current axes.

  • label (str, optional) – Text label. If None provided, assume coordinates are in meters, and add label in kilometers according to the size parameter.

  • loc (str, optional) – Location of the scale bar relative to axes (e.g. ‘upper left’, ‘center right’), default to ‘lower right’. See the loc parameter of matplotlib.axes.Axes.legend for details.

  • size (float, optional) – Bar size in data coordinates. Default to a function of axes area rounded on an approximate log scale (1, 2, 5, 10, 20 km etc).

  • **kwargs (optional) – Additional keyword arguments are passed to the matplotlib.lines.Line2D artist for the scale bar. Default to a black bar with a vertical marker on each end.

Returns:

abs (AnchoredScaleBar) – An anchored container for the scale bar and text label.
