Python Bokeh – 在图上绘制补丁

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补丁。可以使用plotting模块的patch()方法在图上绘制补丁。

plotting.figure.patch()

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 Patch Graph") 
     
# the points to be plotted
x = [0, 1, 2, 3, 4, 5]
y = [5, 2, 8, 5, 0, 10]
      
# plotting the graph 
graph.patch(x, y) 
       
# 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补丁

# 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 Patch 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
x = [0, 0, 1, 1, 4, 2, 8, 4]
y = [2.5, 0.5, 0.5, 2.5, 5, 9, 1, 0]
  
# color value of the patch
color = "yellow"
  
# fill alpha value of the patch
fill_alpha = 0.5
  
# name of the legend
legend_label = "Sample Patch"
  
# plotting the graph 
graph.patch(x, y,
            color = color,
            fill_alpha = fill_alpha,
            legend_label = legend_label) 
       
# displaying the model 
show(graph)

输出 :
