【问题描述】:
我是一名新的 Python 学习者,正在尝试用散景制作一个情节。我想使用悬停工具,当我滚动点时它正在工作。但是,X 和 Y 值显示 ???而不是实际值。我不太确定我做错了什么,因为悬停工具本身正在工作,但值没有显示。
from bokeh.plotting import figure`
from bokeh.io import show, output_notebook
get_provider(Vendors.CARTODBPOSITRON)
from bokeh.models import ColumnDataSource, HoverTool
# Create a blank figure with labels
p = figure(plot_width = 600, plot_height = 600,
title = 'Example Glyphs',
x_axis_label = 'X', y_axis_label = 'Y')
hover = HoverTool(tooltips=[
("X", "@X "),
("Y","@Y")])
p = figure(x_axis_type="mercator",
y_axis_type="mercator",
tools=[hover, 'wheel_zoom','save'])
p.add_tile(CARTODBPOSITRON)
# Example data
circles_x = [1, 3, 4, 5, 8]
circles_y = [8, 7, 3, 1, 10]
circles_x = [9, 12, 4, 3, 15]
circles_y = [8, 4, 11, 6, 10]
# Add squares glyph
p.circle(squares_x, squares_y, size = 12, color = 'navy', alpha = 0.6)
# Add circle glyph
p.circle(circles_x, circles_y, size = 12, color = 'red')
# Set to output the plot in the notebook
output_notebook()
# Show the plot
show(p)
