MetPy - BarbPlot()

MetPy - `BarbPlot()`#

This class is designed to plot wind barbs from gridded data, most commonly model output from the GFS, NAM, or RAP.

Attribute	Description
barblength	A float value that changes the length of the wind barbs.
color	A string value that controls the color of the vectors.
data	Xarray dataset that contains the field to be plotted.
earth_relative	A boolean value to indicate whether the vector to be plotted is earth- or grid-relative.
field	A tuple containing the two components of the vector field from the dataset in the form (east-west component, north-south component).
level	The level of the field to be plotted.
pivot	A string setting the pivot point of the vector.
plot_units	The desired units to plot the field in.
scale	Scale the field to be plotted by the value given.
skip	A tuple of integers to indicate the number of grid points to skip between plotting vectors.
time	Set the valid time to be plotted as a datetime object.
mpl_args	Supply a dictionary of valid Matplotlib keyword arguments to modify how the plot variable is drawn.

This attribute must be set to the variable that contains the vector components to be plotted.

This attribute is a list of the vector components to be plotted. For the typical meteorological case it would be the [‘u-component’, ‘v-component’].

This attribute should be set to a datetime object, the same as for all other declarative classes.

Set this to an integer value to skip the plotting of wind barbs in the x and y directions to thin the number of wind barbs plotted.

This attribute sets the length of the wind barbs. The default value is based on the font size.

This attribute sets the color of the wind barbs, which can be any Matplotlib color. Default color is ‘black’.

This attribute can be set to False if the vector components are grid relative (e.g., for NAM or NARR output)

This attribute can be set to a string value about where the wind barb will pivot relative to the grid point. Possible values include ‘tip’ or ‘middle’. Default is ‘middle’.

This attribute can be set to a dictionary containing keyword arguments (kwarg) valid for the various Matplotlib plotting functions to enhance how a plot is created. For example, you can use this attribute to set the zorder kwarg to alter what aspects of the your plot are on top of one another. NOTE: Setting the mpl_args trait will override any other trait that corresponds to a specific kwarg for the particular plot type (e.g., linecolor, linewidth).
