While plotting two or more vectors using quiver plots arrows heads are scaled with respect to barb length. No option for having arrow heads of fixed size as depicted in attached file. Please add option for the same.Here is the code:
from plotly import tools from plotly.offline import download_plotlyjs, plot, iplot, init_notebook_mode import plotly.graph_objs as go import plotly.figure_factory as ff import numpy as np
init_notebook_mode(connected=True)
layout=go.Layout(xaxis=dict(range=[-10,10],dtick=1), yaxis=dict(range=[-10,10],dtick=1, ticks='outside'), width=900, height=900)
v=np.array([[1,1],[-2,2], [4,7]]) x, y = [0,0,0], [0,0,0] fig= ff.create_quiver(x, y, v[:,0], v[:,1], scale=1) fig.layout.update(layout) iplot(fig)
