如何一次显示两个Bokeh对象？

Question

我正在尝试使用带有RangeTool的Bokeh vbar。我尝试了许多不同的代码行，但这仍然无效。我不明白'浏览器'的错误

相同的代码使用line或scatter

这是错误：

TypeError：类型'Figure'的参数不可迭代

这是下面的代码：

from bokeh.io import show
from bokeh.layouts import column
from bokeh.models import ColumnDataSource, RangeTool
from bokeh.plotting import figure
from bokeh.models import Range1d

x = [1,2,3,4,5,6,7,8]
wdth = [0.5 for x in range(0,8)]
top = [8,7,6,5,4,3,2,1]

sourceRT5 = ColumnDataSource(data=dict(x=x, width=wdth, top=top))
p = figure(plot_height=300, plot_width=800, 
           tools="", toolbar_location=None,
           x_axis_type="linear")


p.vbar('x', 'width', 'top', bottom=0, line_color='dodgerblue', 
       fill_color="dodgerblue", legend='New Words',
        source=sourceRT5)

p.yaxis.axis_label = 'Price'

select = figure(plot_height=50, plot_width=800, y_range=(0,10),
                x_axis_type="linear",  y_axis_type=None,
                tools="", toolbar_location=None)

range_rool = RangeTool(x_range=Range1d(3,8))
range_rool.overlay.fill_color = "navy"
range_rool.overlay.fill_alpha = 0.2

select.vbar('x', 'width', 'top', source=sourceRT5)
select.ygrid.grid_line_color = None
select.add_tools(range_rool)
select.toolbar.active_multi = range_rool

show(p,select)

看来你正试图显示多个数字。 show采用它应该显示的单个对象，第二个参数是它应该用于哪个浏览器（例如firefox，chrome，IE，vivaldi，......）。虽然你写的它与散点图一起工作，我猜它没有抛出错误但实际上没有用。

散景有一些documentation on displaying multiple plots。短版本是你需要告诉它应该以哪种方式布局它。一个非常通用的功能是layout：

from bokeh.layouts import layout
... # your code without show(...)
show(layout([p,select]))
