HoverTool for Stacked vBar on Bokeh

hi,

I am not very sure how to make the hovertool to work on a stacked vbar. my guess is not input the right data to the hovertool? the code is below

from bokeh.core.properties import value

from bokeh.plotting import figure, show

from bokeh.models import ColumnDataSource

from bokeh.models import HoverTool

fruits = [‘0’,‘1’,‘2’,‘3’,‘4’,‘5’,‘6’,‘7’,‘8’,‘9’,‘10’,‘11’,‘12’,‘13’,‘14’,‘15’,‘16’,‘17’,‘18’,‘19’,‘20’,‘21’,‘22’,‘23’]

colorType = [“blueNums”, “greenNums”]

colors = [“blue”, “green”]

data = {‘fruits’ : fruits,

‘blueNums’ : [2, 1, 4, 3, 2, 4, 1, 4, 3, 2, 4,5, 3, 4, 2, 4, 6, 1, 4, 3, 2, 4,2,2],

‘greenNums’ : [5, 3, 4, 2, 4, 6, 1, 4, 3, 2, 4,5, 3, 4, 2, 4, 6, 1, 4, 3, 2, 4,2,2],

}

source = ColumnDataSource(data=data)

p = figure(x_range=fruits, plot_width=1000, title=“Fruit Counts by Year”,

toolbar_location=“right”, tools=“reset,pan”)

r1 = p.vbar_stack(colorType, x=‘fruits’, width=0.9, color=colors, source=source,

legend=[value(x) for x in colorType])

hover = HoverTool(renderers=[r1])

hover.tooltips=[ (“Blue_hover”, “$blueNums”),(“Green_hover”, “$sellNums”) ]

p.add_tools(hover)

show§

Thanks.
