如何在具有bokeh后端的全息视图中控制(活动)工具 [英] How to control (active) tools in holoviews with bokeh backend

问题描述

如何通过bokeh后端控制在holoviews图中使用/激活哪些工具?我已经看过这个SO答案，但是只有添加一个新的活动工具；不会阻止其他任何工具(例如平移)处于活动状态.

How do I control which tools are used / active in a holoviews plot with the bokeh backend? I've seen this SO answer, but that only adds a new active tool; it doesn't keep any other tools (e.g. pan) from being active.

对于一个特定的示例，假设我只想要悬停工具.我会尝试这样做:

For a specific example, suppose I only want the hover tool. I would try doing this:

import holoviews as hv
hv.extension("bokeh")
hv.Curve([1, 2, 3]).opts(tools=["hover"])

，但最后我得到了一个情节，该情节除了默认工具外还悬停了 .如何指定要使用的所有工具列表，以便不使用不在该列表中的工具?

but then I end up with a plot that has hover in addition to the default tools. How do I specify the list of all tools that I want to use, so that no tools are used that aren't in that list?

类似地，如何指定所有活动工具的列表?例如

Similarly, how do I specify the list of all active tools? E.g.

import holoviews as hv
hv.extension("bokeh")
hv.Curve([1, 2, 3]).opts(tools=["hover"], active_tools=[])

让我平移和悬停都活跃起来；我希望悬停是唯一的工具，但没有要激活的工具.

gives me both pan and hover being active; I want hover to be the only tool but no tool to be active.

推荐答案

对于第一个问题，请使用default_tools选项:

For your first question, use default_tools option:

hv.Curve([1, 2, 3]).opts(tools=["hover"], default_tools=[])

提出第二个问题，holoviews中没有方法可以执行此操作，但是您可以将其直接设置为Figure对象:

fot the second question, there is not method in holoviews to do this, but you can set it to the Figure object directly:

def set_tools(plot, element):
    plot.state.toolbar.active_drag = None

hv.Curve([1, 2, 3]).opts(finalize_hooks=[set_tools])
