Removing legend title

HoloViews
1 
import xarray as xr
import hvplot.xarray
ds = xr.tutorial.open_dataset('air_temperature').mean(['lat', 'lon'])
ds['airx2'] = ds['air'] * 2
ds = ds.to_array().rename('test')
ds.hvplot('time', by='variable')

Is there a way to remove legend title variable?

In holoviews, this gives you what you want.

h = ds.hvplot('time', by='variable')
h.get_dimension('variable').label=''

There is a h.redim.label function also but I don’t manage to make it work.

Besides, there is always the possibility to finely tune what you want on the bokeh side of things.

    import holoviews as hv
    from bokeh.io import show
    h = ds.hvplot('time', by='variable')
    fig = hv.renderer('bokeh').get_plot(h).state
    fig.legend.to_json(include_defaults=False)

This last line indicates what can be changed about the legend:

    {'click_policy': 'mute',
    'id': '2395',
    'items': [{'id': '2396'}, {'id': '2427'}],
    'location': [0, 0],
    'title': 'variable'}

These next lines yield the desired result:

fig.legend.title = ''
show(fig)
