Python Bokeh – 在图表上绘制破折号

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 可用于在图表上绘制虚线。可以使用plotting模块的dash()方法在图表上绘制破折号。

plotting.figure.dash()

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 Dash Graph")
   
# the points to be plotted
x = [-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]
y = [25, 16, 9, 4, 1, 0, 1, 4, 9, 16, 25]
    
# plotting the dashes
graph.dash(x, y)
    
# displaying the model
show(graph)

输出 :

示例 2:在此示例中,我们将在其他参数旁边绘制带有虚线的破折号。

# 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 Dash Graph")
  
# name of the x-axis
graph.xaxis.axis_label = "x-axis"
   
# name of the y-axis
graph.yaxis.axis_label = "y-axis"
  
# the points to be plotted
x = [-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5]
y = [25, 16, 9, 4, 1, 0, 1, 4, 9, 16, 25]
  
# size of the dashes
size = 20
  
# angle of the dashes
angle = 10
  
# color of the line
line_color = "red"
   
# type of line
line_dash = "dotted"
   
# offset of line dash
line_dash_offset = 1
  
# width of the dashes
line_width = 10
  
# name of the legend
legend_label = "Sample Dashes"
   
# plotting the line graph for AAPL
graph.dash(x, y,
           size = size,
           angle = angle,
           line_color = line_color,
           line_dash = line_dash,
           line_dash_offset = line_dash_offset,
           line_width = line_width,
           legend_label = legend_label)
    
# plotting the dashes
graph.dash(x, y)
    
# displaying the model
show(graph)

输出 :
