Label position and change Discret slider to rangeslider

I would like to change the label position and change the slider to a range slider. The following code is a eksempel. I have tried every thing but without success.

import xarray as xr
import hvplot.xarray # noqa
import numpy as np

ds = xr.tutorial.open_dataset(‘air_temperature’).load()
lon = [-55]
lat = [66]
air = ds[‘air’].sel(lon=lon,lat=lat,method=‘nearest’)-273.15
gb = air.groupby(‘time’)
gb1 =

lon1 = [-50]
lat1 = [60]
air2 = ds[‘air’].sel(lon=lon1,lat=lat1,method=‘nearest’)-273.15
air2_2 = air2.groupby(‘time’)
gb2 =

ss=gb1.hvplot(color =‘red’,grid=True,label=‘Position 1’,groupby=[‘time.year’,‘time.month’]).opts(bgcolor=‘lightgrey’)
ss1=gb2.hvplot(color=‘green’,grid=True,label=‘Position 2’,groupby=[‘time.year’,‘time.month’]).opts(bgcolor=‘lightgrey’)

ls = ss * ss1
