Holoviews 中的水平滚动条

如何解决Holoviews 中的水平滚动条

我使用 Holoviews 进行了交互式可视化，并希望在绘图底部有一个水平滚动条。我目前使用可以控制图中列数的滑块，但我也更喜欢使用水平滚动条。因此，通过增加行业数量，图的宽度和列的宽度不会改变。 这是我的代码和情节：

import pandas as pd
import panel as pn
import panel.widgets as pnw
import holoviews as hv
from bokeh.plotting import figure
hv.extension('bokeh')

from bokeh.models import HoverTool,BoxZoomTool,ResetTool,PanTool,WheelZoomTool,Savetool,LassoSelectTool

data = df 
Options = ["All"] + list(data['country_code'].unique())
xlist = list(data['Industry'].unique())
Countries = pn.widgets.Select(name = "Country",options = Options,value = "All")
x = pn.widgets.IntSlider(name = 'Industry',value = 10,start = 10,end = 30)


hover = HoverTool(description='Custom Tooltip',tooltips = [('Industry','@Title'),('Count','@Count')])

@pn.depends(Countries.param.value,x.param.value)

def fig(Countries,x):
   
    opts = dict(title = "Companies by Industry",width = 50*x,height = 300,line_color = 'black',tools = [hover],apply_ranges = True)




# Determine which country has been selected

    if Countries == "All":
        selected = data.groupby(['Industry']).sum().reset_index().rename(columns = {0:'Count'}).sort_values(by ='Count',ascending = False )[:x]
    
    else:
        selected = data[data['country_code'] == Countries].sort_values(by ='Count',ascending = False )[:x]
    
    selected['Title'] = 'title'


    return hv.Bars(selected,'Industry','Count').opts(**opts)

widgets = pn.WidgetBox(Countries,x)
pn.Column(widgets,fig)

另外一点，我想向悬停工具添加另一个变量（此处称为标题），但它显示在所有列中，例如 ???。我不知道为什么这些值没有正确传递给悬停工具。

解决方法

可以在此处找到解决方案： https://discourse.holoviz.org/t/horizontal-scroll-in-holoviews/2516

只需要将最后一行更改为类似 pn.Column(widgets,pn.Column(fig,scroll=True,width=500))
