Description

The BoxWhisker doesn't seem to show the outliers when there is a space or a bracket in the name of the data. The y limits are still set as if the outliers are included, but the outliers are not shown. Only the y-axis name has an influence, the x-axis name can have spaces or brackets without having an effect on the outliers.

Example

import holoviews as hv
import pandas as pd

df = pd.DataFrame({'data':  [1,2,4,5,2,3,3,2,20,34],
                   'data 2':[1,2,4,5,2,3,3,2,20,34],
                   'data[': [1,2,4,5,2,3,3,2,20,34],
                   'x':     [1,1,1,1,1,1,1,1,1,1]})

(hv.BoxWhisker(df, 'x', 'data', label='data')+
 hv.BoxWhisker(df, 'x', 'data 2', label='data 2')+
 hv.BoxWhisker(df, 'x', 'data[', label='data[')+
 hv.BoxWhisker(df, 'x[', 'data', label='x['))
