散景链接刷与自定义索引

Question

假设我有一个 table 列：id、x1、y1、x2、y2。我想并排绘制 x1 vs y1 和 x2 vs y2，并通过 id 链接刷牙。关于链接刷亮的 Bokeh 文档 here 仅显示两个绘图共享同一个轴时的示例。

如何使用 Bokeh 执行此操作？

Answer 1

用同样的例子，这不是你想要的吗？每个图都有不同的 x 和 y，但仍然有联系？

from bokeh.io import output_file, show
from bokeh.layouts import gridplot
from bokeh.models import ColumnDataSource
from bokeh.plotting import figure

output_file("brushing.html")

x = list(range(-20, 21))
x2 =list(range(-30, 10))
y0 = [abs(xx) for xx in x]
y1 = [xx**2 for xx in x2]

# create a column data source for the plots to share
source = ColumnDataSource(data=dict(x=x, x2=x2, y0=y0, y1=y1))

TOOLS = "box_select,lasso_select,help"

# create a new plot and add a renderer
left = figure(tools=TOOLS, width=300, height=300, title=None)
left.circle('x', 'y0', source=source)

# create another new plot and add a renderer
right = figure(tools=TOOLS, width=300, height=300, title=None)
right.circle('x2', 'y1', source=source)

p = gridplot([[left, right]])

show(p)
