散景：仅显示一个工具提示
Arn*_*uza 3 python python-2.7 python-3.x pandas bokeh
我面临与在散景图中正确显示 HoverTool 工具提示相关的问题。我的目的是只显示一个，使用属性：
模式 = vline
如下图所示：
但是，我的绘图为 vline 在与图形交互期间穿过的每个字形（系列）呈现一个工具提示，如下所示：
即使我将属性 Mode 更改为“鼠标”，该图仍会继续呈现多个工具提示：

您可以定义glyphrenderer要附加到悬停工具的内容。为此，首先命名您的字形，例如
r1 = p.vbar(...)
然后将renderers参数添加到悬停 -
hover.renderers =[r1]
