Different Hovertool for Different Data Series - Same Plot

I would like to be able to have a different HoverTool for different datasets inside the same Bokeh figure. For example, the first series would have tooltips for “Date, Name” and the second series would have tooltips for “User, Typer”.

The code is am using is below. When HoverTools is called a second time it erases the tooltips from the first series. Is there a way to have different tooltips for different data series?

import numpy as np

import bokeh.plotting as bp

from bokeh.models import HoverTool, ColumnDataSource

from collections import OrderedDict

bp.output_file(‘test.html’)

fig = bp.figure(tools=“reset,hover”)

x = np.linspace(0,2*np.pi)

y1 = np.sin(x)

y2 = np.cos(x)

test = [‘test’] * len(y2)

source = ColumnDataSource(data = dict(test = test))

s1 = fig.scatter(x=x,y=y1,color=’#0000ff’,size=10,legend=‘sine’)

s1.select(dict(type=HoverTool)).tooltips = {“x”:"$x", “y”:"$y"}

s2 = fig.scatter(x=x,y=y2,color=’#ff0000’,size=10,legend=‘cosine’)

hover = s2.select(dict(type=HoverTool))

hover.tooltips = OrderedDict([(‘Test’, ‘@test’)])

bp.show(fig)
