Python Bokeh–制作互动传说
原文:https://www . geesforgeks . org/python-bokeh-making-interactive-legends/
Bokeh 是一个 Python 交互式数据可视化工具。它使用 HTML 和 JavaScript 来渲染它的图。它以现代网络浏览器为呈现目标，提供优雅、简洁的新颖图形结构和高性能交互性。
如何制作互动传奇？
图表的图例反映了图表 Y 轴中显示的数据。在博克，传说对应于字形。有两种方法可以使图例互动:
- 隐藏
- 叛变
隐藏字形
通过将图例 click_policy 属性设置为“隐藏”，可以从图例中隐藏字形。
示例:
Python 3
# importing the modules
from bokeh.plotting import figure, output_file, show
# file to save the model
output_file("gfg.html")
# instantiating the figure object
graph = figure(title = "Bokeh Hiding Glyphs")
# plotting the graph
graph.vbar(x = 1, top = 5,
width = 1, color = "violet",
legend_label = "Violet Bar")
graph.vbar(x = 2, top = 5,
width = 1, color = "green",
legend_label = "Green Bar")
graph.vbar(x = 3, top = 5,
width = 1, color = "yellow",
legend_label = "Yellow Bar")
graph.vbar(x = 4, top = 5,
width = 1, color = "red",
legend_label = "Red Bar")
# enable hiding of the glyphs
graph.legend.click_policy = "hide"
# displaying the model
show(graph)
输出:

隐藏字形使其完全消失，另一方面，静音字形只是根据参数取消强调字形。通过将图例 click_policy 属性设置为“静音”，可以将图例中的字形静音。
Python 3
# importing the modules
from bokeh.plotting import figure, output_file, show
# file to save the model
output_file("gfg.html")
# instantiating the figure object
graph = figure(title = "Bokeh Hiding Glyphs")
# plotting the graph
graph.vbar(x = 1, top = 5,
width = 1, color = "violet",
legend_label = "Violet Bar",
muted_alpha=0.2)
graph.vbar(x = 2, top = 5,
width = 1, color = "green",
legend_label = "Green Bar",
muted_alpha=0.2)
graph.vbar(x = 3, top = 5,
width = 1, color = "yellow",
legend_label = "Yellow Bar",
muted_alpha=0.2)
graph.vbar(x = 4, top = 5,
width = 1, color = "red",
legend_label = "Red Bar",
muted_alpha=0.2)
# enable hiding of the glyphs
graph.legend.click_policy = "mute"
# displaying the model
show(graph)
