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(p)
Thanks.
