Python Bokeh Hover Tool giving: AttributeError: unexpected attribute 'tooltips' to Figure

问题

How do I implement "tooltips" for the hover tool in Bokeh 0.12.11 (and possibly other versions)?

Searching for "Bokeh hover tooltips" gives a bunch of documentation results such as: https://docs.bokeh.org/en/latest/docs/user_guide/tools.html

But when I try to implement the "tooltips" on Bokeh 0.12.11 from an example such as: https://docs.bokeh.org/en/latest/docs/gallery/elements.html

I get the following error: AttributeError: unexpected attribute 'tooltips' to Figure, possible attributes are above, aspect_scale, etc.

回答1:

Solution:

I removed the TOOLTIP= [] declaration, and the tooltips= parameter in the figure() object.

Make the Hover Tool programatically and attach to Figure:

from bokeh.models import HoverTool

{ some code }

p = figure(tools=TOOLS, title=TITLE, x_axis_label='Pressure (mTorr)', y_axis_label='Roughness (nm)')

hover = HoverTool()

hover.tooltips = [
    ("Sample", "@names"),
    ("Pressure", "@x_values mTorr"),
    ("Roughness", "@y_values nm"),
]

p.tools.append(hover)

As pointed out here: Python Bokeh HoverTool formatters error: "unexpected attribute 'formatters' to HoverTool"

version 0.12.11 supports it but I was having trouble implementing it.

Thanks to bigreddot for pointing out that passing that parameter only works in 0.13.
