I am trying to create a Holomap figure in holoviews that includes a legend at the top of the plot.
The configuration option "legend_position" works fine for a non-holomap figure ("example1.html" below), but not for the holomap ("example2.html" below).
import pandas as pd
import holoviews as hv
df = pd.DataFrame(dict(x=[1, 2], y1=[0, 1], y2=[1, 0], y3=[0.8, 0.8], y4=[0.2,0.2]))
curve1 = hv.Curve(df, 'x', 'y1', label='curve1').opts(ylabel='y')
curve2 = hv.Curve(df, 'x', 'y2', label='curve2').opts(ylabel='y')
curve3 = hv.Curve(df, 'x', 'y3', label='curve3').opts(ylabel='y')
curve4 = hv.Curve(df, 'x', 'y4', label='curve4').opts(ylabel='y')
cc12 = (curve1 * curve2).opts(legend_position='top')
hv.save(cc12, "example1.html")
cc34 = (curve3 * curve4).opts(legend_position='top')
hm = hv.HoloMap({'a':cc12, 'b':cc34}, kdims=["option"])
hm = hm.opts(legend_position='top')
hv.save(hm, "example2.html")
I think this has something to do with the position of the legend not being allowed outside of the plot in the holomap case. So the answer the question might simply be "It is not supposed to work". The problem is that for some plots the default legend overlaps with the curves, making the curves hard to interpret.
