Python Bokeh – 在图表上绘制线段

Bokeh 是一个Python交互式数据可视化。它使用 HTML 和 JavaScript 渲染其绘图。它针对现代 Web 浏览器进行演示，提供具有高性能交互性的新颖图形的优雅、简洁构造。

Bokeh 可用于在图形上绘制线段。可以使用plotting模块的segment()方法在图形上绘制线段。

plotting.figure.segment()

Syntax : segment(parameters)

Parameters :

x0 : x-coordinates of the starting points of the line segment
y0 : y-coordinates of the starting points of the line segment
x1 : x-coordinates of the ending points of the line segment
y1 : y-coordinates of the ending points of the line segment

Returns : an object of class GlyphRenderer

编程需要懂一点英语

示例 1：在此示例中，我们将使用默认值来绘制图形。

# 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 Segment Graph")
      
# the points to be plotted
x0 = 0
y0 = 0
x1 = 10
y1 = 10
  
# plotting the graph
graph.segment(x0, y0,
              x1, y1)
      
# displaying the model
show(graph)

输出：

示例 2：在此示例中，我们将使用各种其他参数绘制多条线段

# 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 Segment Graph") 
  
# name of the x-axis 
graph.xaxis.axis_label = "x-axis"
       
# name of the y-axis 
graph.yaxis.axis_label = "y-axis"
  
# points to be plotted
x0 = [0, 0, 5]
y0 = [0, 5, 0]
x1 = [10, 10, 5]
y1 = [10, 5, 10]
  
# color of the lines
line_color = ["yellow", "red", "purple"]
  
# value of line dash
line_dash = "dotted"
  
# thickness of the lines
line_width = [15, 10, 20]
  
# plotting the graph 
graph.segment(x0, y0,
              x1, y1,
              line_color = line_color,
              line_dash = line_dash,
              line_width = line_width) 
       
# displaying the model 
show(graph)
