Get the Values of a Rangeslider

Panel
4

Carl’s approach is good too, but if you want to stay closer to your original example, the key is that inside the function, there’s no slider, just a value, so you don’t have to ask for the value. (The error message indicates that it’s already a tuple, not a slider whose value you need to request.) Panel’s depends decorator is already taking care of pulling that value out and supplying it to the function. To make that clear, I’ve renamed your Slider and Ensemble names to be lower case (always reserving upper case for class names for clarity), and also renamed Slider inside the function so that you can distinguish between the slider widget object (now called slider) and the value of the slider (slider.value, provided by Panel as a tuple called xrange to the ensemble function). Hope this helps!

import holoviews as hv
import panel as pn
from panel import widgets as pnw
import numpy as np
hv.extension('bokeh')
coords = np.random.rand(50,2)
points = hv.Points(coords)
slider = pnw.RangeSlider(start=0, step=0.1, end=1, name='Zeitraum')

@pn.depends(xrange=slider)
def ensemble(xrange):
    points=hv.Points(coords)
    points.opts(color='k', marker='+', xlim=xrange)
    return pn.Row(points)
pn.Row(ensemble, slider)
