Настройка HoverTool

from bokeh.models import ColumnDataSource
source = ColumnDataSource(data=nba)

TOOLTIPS = [("Name", "@player"), ("Team", "@team")]

fig = figure(x_axis_label="Assists", y_axis_label="Points",

             tooltips=TOOLTIPS)

fig.circle(x="assists", y="points", source=source)
output_file("name_and_team.html")

HoverTool

Отображение числовых данных

TOOLTIPS = [("Name", "@player"), ("Team", "@team"),

            ("Points", "@points"), ("Assists", "@assists")]

fig = figure(x_axis_label="Assists", y_axis_label="Points", tooltips=TOOLTIPS)
fig.circle(x="assists", y="points", source=source)
output_file("hovertool.html")

HoverTool без форматирования

Форматирование HoverTool

TOOLTIPS = [("Name", "@player"), ("Team", "@team"),

            ("Points", "@points{0.2f}"), ("Assists", "@assists{0.2f}")]

fig = figure(x_axis_label="Assists", y_axis_label="Points", tooltips=TOOLTIPS)
fig.circle(x="assists", y="points", source=source)
output_file("formatted_hovertool.html")
show(fig)
