如何在工具栏中不显示多个图标的情况下添加多个悬停工具? [英] How to add multiple Hover Tools without showing multiple icons in the toolbar?

问题描述

以下示例

是否可以添加多个悬停工具，并使工具栏与其他工具一起可见，但不能复制悬停图标?

解决方案

只需将 toggleable 属性设置为 False .请检查隐藏鼠标悬停工具按钮的此示例:

从bokeh.models中的

 导入HoverTool，ColumnDataSource，LassoSelectTool，PanTool来自bokeh.plotting进口展览，人物，curdoc源= ColumnDataSource(dict(x = [1、2、3、4]，y = [5，6，7，8]))p =数字(宽度= 400，高度= 400，工具='')p.scatter(x ='x'，y ='y'，source = source，fill_alpha = 1.0，line_alpha = 1.0，line_color =灰色"，大小= 6)pan = PanTool()套索= LassoSelectTool()工具提示='''< b> X:</b>@ {x}< br>< b> Y:</b>@ {y}< br>'''悬停= HoverTool(toggleable = False，#将其添加到所有悬停工具中模式='鼠标'，工具提示=工具提示，)工具=(锅，套索，悬停)p.add_tools(*工具)curdoc().add_root(p) 

好吧，如果您只想使用一个按钮，则可以只使用一个悬停工具.模型 CustomJSHover 可能对您有用.

作为解决方法，您还可以更新每个鼠标悬停的 renderers 属性.

Following the example here I have added multiple tooltips to a stacked bar chart. I also want to have other tools available in the toolbar above the plot, but when multiple hover tools are created using the process in the example it creates multiple icons in the tool bar, leaving it looking messy like this:

Is there a way to add multiple hover tools, and have the toolbar visible with other tools in it, but not duplicate the hover icon?

解决方案

Just set the toggleable attribute to False. Check this example, where the hover tool button is hidden:

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)

Well, and if you want to use only one button then you might use only one hover tool. The model CustomJSHover may be useful for you.

As a workaround you can also update the renderers attribute of each hover pressing some button or custom tool.
