Hello,
I want to add some vertical lines on the same plot with boxwhisker
import holoviews as hv
from holoviews import dim
hv.extension('bokeh')
from bokeh.sampledata.autompg import autompg as df
title = "MPG by Cylinders and Data Source, Colored by Cylinders"
boxwhisker = hv.BoxWhisker(
df, ['cyl', 'origin'], 'mpg', label=title
).opts(
show_legend=False, width=600, box_fill_color=dim('origin').str(), cmap='Set1'
)
Overlay
with list of VLine
like
vlines = [hv.VLine(i).opts(color='red', line_width=1.0) for i in range(1, 10, 2)]
import functools
import operator
boxwhisker * functools.reduce(operator.mul, vlines)
works well:
But Overlay
with VLines
like
vlines = hv.VLines([i in range(1, 10, 2)])
vlines.opts(color='red', line_width=1)
boxwhisker * vlines
prints
:Overlay
.BoxWhisker.MPG_by_Cylinders_and_Data_Source_comma_Colored_by_Cylinders :BoxWhisker [cyl,origin] (mpg)
.VLines.I :VLines [x]
and raises Exception:
...
ValueError: not enough values to unpack (expected 2, got 1)
