This is happening because names isn’t a column on the data source that’s driving your plot.
The short answer is use @cat.
You can see the data source that’s driving the plot as follows:
glyph_ renderers = bar.select(dict(type=GlyphRenderer))
bar_source = glyph_renderers.data_source
Hope that helps.

I have a data in which one column is a list of names. Can I make a custom hover tooltip for bar charts to work ?
from bokeh.charts import Bar
from bokeh.models import HoverTool
numbers = [1, 2, 3, 4, 5]
names = ['a', 'b', 'c', 'd', 'e']
bar = Bar(numbers, names, tools='hover')
hover = bar.select(dict(type=HoverTool))
hover.tooltips = [
For position, the hover is working fine, but for ‘name’ it shows ‘???’. Any idea how to make it work ? Or am I making something wrong ?
