hvPlot.vectorfield

hvPlot.vectorfield(x=None, y=None, angle=None, mag=None, **kwds)

vectorfield visualizes vectors given by the (x `, `y) starting point, a magnitude (mag) and an angle. A vectorfield plot is also known as a quiver plot.

Reference: https://hvplot.holoviz.org/reference/xarray/vectorfield.html

Parameters:

xstring

Field name to draw x-positions from

ystring

Field name to draw y-positions from

magstring

Magnitude

anglestring

Angle in radians.

**kwdsoptional

Additional keywords arguments are documented in hvplot.help(‘vectorfield’). See Plotting Options for more information.

Returns:

holoviews.element.Points / Panel object

You can print the object to study its composition and run:

import holoviews as hv
hv.help(the_holoviews_object)

to learn more about its parameters and options.
