Python Bokeh – 在图上绘制多个补丁

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多个补丁。可以使用plotting模块的patches()方法在图上绘制多个补丁。

plotting.figure.patches()

Syntax : patches(parameters)

Parameters :

• xs : x-coordinates of the patches
• ys : y-coordinates of the patches

Returns : an object of class GlyphRenderer

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 Patches Graph") 
     
# the points to be plotted
xs = [[1, 2, 3], [3, 5, 3, 5]]
ys = [[1, 2, 1], [2, 2, 4, 5]]
      
# plotting the graph 
graph.patches(xs, ys) 
       
# 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 Patches 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
xs = [[1, 2, 3], [3, 5, 5, 3]]
ys = [[1, 2, 1], [4, 4, 2, 2]]
  
# color value of the patches
color = ["green", "red"]
  
# fill alpha value of the patches
fill_alpha = 1
  
# plotting the graph 
graph.patches(xs, ys,
              color = color,
              fill_alpha = fill_alpha) 
       
# displaying the model 
show(graph)
