Description Of Changes
This PR implements a number of improvements to the declarative interface to allow for additional kwargs to alter how a data element is plotted. Primarily this adds a new trait called
mpl_args
for all declarative plot classes and is designed to be a dictionary of values. Additionally, this PR adds thestroke_width
trait for PlotGeometry since it would be a heavily used element that we wish to expose according to issue #2719. This would also allow for more nuanced use of alpha and zorder as discussed in #2746.Checklist
PlotGeometry
missing trait for stroke width #2719 and Zorder for metpy.BarbPlot #2746
