【中文标题】如何删除散景中悬停收费的“屏幕信息”？

【英文标题】：how can I remove the "screen information" of hover tolls in bokeh?

【问题描述】：

我使用散景绘制了一个绘图，此外，我使用了“悬停”工具来查看点的值。但我还看到另一个值调用：“屏幕”我想禁用这些值的呈现

我已经尝试了不同的方法，但它不起作用

这是我的代码

tools = ["hover","crosshair","box_select","box_zoom","wheel_zoom","reset"]
            p = figure(title=self.select_recension, width=1000, height=800, x_range=(1.5, 22), y_range=(35.5, 47),tools=tools)
            for i in self.fs_dict.values():
                p.line(i[:,0],i[:,1], color="dodgerblue",legend="Boundary in Omega",line_width=1.5)
            co="dfTemp"
            p.circle(np.array(self.df_dict[co]['longitude']),np.array(self.df_dict[co]['latitude']), fill_color="dodgerblue",size=6,fill_alpha=.9,line_color="dodgerblue",line_alpha=0.6,legend="Localities in Omega",muted_alpha=0.2)
            for i in self.gs_dict.values():
                p.line(i[:,0],i[:,1], color="red",legend="Boundary in Xi",line_dash="dashdot",line_width=1.5)
            co='dfTempX'
            p.circle(np.array(self.df_dict[co]['longitude']),np.array(self.df_dict[co]['latitude']), fill_color="crimson",size=6, fill_alpha=.9, line_color="red",line_alpha=0.6,legend="Localities in Xi")
            p.legend.click_policy="hide"
            show(p)

正如您在此处看到的，当我将鼠标放在“数据”和“屏幕”上时，我想禁用显示屏幕部分。

【参考方案1】：

如果您想显示默认工具提示以外的其他内容，则应在 figure() 中指定工具提示。工具提示应指定为 (label, value) 元组的列表。以 $ 开头的字段是“特殊字段”，例如屏幕位置、索引或字形渲染器的名称。以 @ 开头的字段与 ColumnDataSource 中的列相关联。您想要显示数据源中的 x/y 位置，因此您应该将 @x 和 @y 添加到工具提示中。有关悬停工具和工具提示的更多信息，请参阅this 页面上的文档。

from bokeh.plotting import figure, output_file, show, ColumnDataSource

output_file("toolbar.html")

source = ColumnDataSource(data=dict(
    x=[1, 2, 3, 4, 5],
    y=[2, 5, 8, 2, 7],
    desc=['A', 'b', 'C', 'd', 'E'],
))

TOOLTIPS = [
    ("index", "$index"),
    ("(x,y)", "($x, $y)"),
    ("desc", "@desc"),
]

p = figure(plot_width=400, plot_height=400, tooltips=TOOLTIPS, title="Mouse over the dots", tools="pan,wheel_zoom,hover,reset")

p.circle('x', 'y', size=20, source=source)

show(p)

【讨论】：

感谢您的回复，我已经阅读了该链接，我认为有一种更简单的方法可以使屏幕处于非活动状态，我会尝试您的解决方案，然后告诉您！

【参考方案2】：

这就是答案
