Migrating from SO.

The following code creates a DynamicMap allowing you to choose from two variables:

import holoviews as hv
import pandas as pd
import numpy as np

df = pd.DataFrame()
df['time'] = pd.date_range('2018-01-01', '2018-01-31')
df['var1'] = np.linspace(0, 1, len(df['time']))
df['var2'] = np.ones(df['var1'].shape)

def load_symbol(var):
    return hv.Curve(df, ('time', 'Time'), var)

variables = ['var1', 'var2']
dmap = hv.DynamicMap(load_symbol, kdims='Variable').redim.values(Variable=variables)

dmap.opts(framewise=True, tools=['hover'])

However, the hover tool continues to show the value for var1 even when plotting var2.

Correct behavior for var1:

The tooltip still shows the var1 value of 0.2, but it should read 1.

What's going on here?

Thank you, this is indeed a bug. Originally HoloViews did not support changing the dimensions of an element, this changed a long time ago but it seems like we never implemented updates to the HoverTool tooltips.
