如何添加多个悬停工具而不在工具栏中显示多个图标?

只要设定 toggleable False . 选中此示例,其中悬停工具按钮处于隐藏状态:

from bokeh.models import HoverTool, ColumnDataSource, LassoSelectTool, PanTool
from bokeh.plotting import show, figure, curdoc

source = ColumnDataSource(dict(
    x=[1, 2, 3, 4],
    y=[5, 6, 7, 8]
))

p = figure(
    width=400,
    height=400,
    tools='')

p.scatter(
    x='x', y='y', source=source,
    fill_alpha=1.0, line_alpha=1.0, line_color="grey",
    size=6
)

pan = PanTool()
lasso = LassoSelectTool()

tooltips = '''
    <b>X: </b> @{x} <br>
    <b>Y: </b> @{y} <br>
'''
hover = HoverTool(
    toggleable=False,       # add this to all your hover tools
    mode='mouse',
    tooltips=tooltips,
)

tools = (
    pan, lasso, hover
)
p.add_tools(*tools)

curdoc().add_root(p)

如果你只想使用一个按钮,那么你可以只使用一个悬停工具。模型 CustomJSHover
