Holoviews 酒吧忽略 .opts()

Question

我正在尝试传递 .opts() 参数来设置 holoviews .Bars 图的样式，但传递时所有参数都被忽略。这会导致以下错误： 警告：param.Bars02978：在下一个主要版本 (1.14.0) 中将弃用使用 call 设置选项。请改用等效的 .opts 方法。 我的版本是 1.14.8。我怎样才能传递 .opts() 以便我的图形可以适当地设置样式？

#load data into a DataFrame object:
df = pd.DataFrame(data)
print(df)
df2 = pd.DataFrame({'Missing Data': df[['calories']].sum(axis=1), 'Delayed Data': df[['duration']].sum(axis=1)
                       , 'Duplicate Data': df[['ggg']].sum(axis=1)})
print(df2)

bar_opts = opts.Bars(height=400, width=600, tools=["hover"], bgcolor="grey", xlabel="Wine Class", ylabel="Malic Acid", ylim=(0.0, 3.5))
bars = hv.Bars(pd.melt(df2.reset_index(), ['index']), ['index', 'variable'], 'value', label='dl_refined_analytics').opts(bar_opts)
bars.opts(height=400, width=600, tools=["hover"], bgcolor="grey", xlabel="Wine Class", ylabel="Malic Acid", ylim=(0.0, 3.5))
dmap = hv.DynamicMap(bars)

app = pn.Row(dmap)

app.show() ```

Answer 1

hv.DynamicMap(bars) 背后的意图是什么？我不确定您为什么要将 bars 对象传递给 DynamicMap 构造函数，如果您只使用 app = pn.Row(bars) 而不是 app = pn.Row(dmap) 它应该可以正常工作。
