arrow_plot

A simple function to plot a series of points connected by arrows in matplotlib

Uses the scatter and quiver functions to draw a series of markers, connected them with lines, and place arrows half-way along each line. To use:

arrow_plot(ax,x,y,color='blue',quiver_thickness=0.005,edgecolor=blue,facecolor=blue,marker='o')

The kwargs are of course optional. ax can be a matplotlib subplot, or the matplotlib.pyplot object. x and y are the coordinates of the points, in order.

matplotlib uses a different scaling for quiver arrows than for plot lines, so the thicknesses won't be consistent with a plot of the same linewidth.
