@jbednar, this works great, but if I change the slider widget to “Select” using widgets={'time':pn.widgets.Select} thusly, it bombs:
import panel as pn
import numpy as np
import xarray as xr
import holoviews as hv
import hvplot.xarray
pn.extension()
ds = xr.tutorial.open_dataset('air_temperature')
image = ds.hvplot('lon', 'lat', widgets={'time':pn.widgets.Select})
stream = hv.streams.Tap(source=image, x=-88 + 360, y=40)
def timeseries(x, y):
return ds.sel(lon=x, lat=y, method='nearest').hvplot('time')
pn.Column(image, pn.bind(timeseries, x=stream.param.x, y=stream.param.y))
with the error:
---------------------------------------------------------------------------
