Python Bokeh - Plotting Multiple Patches on a Graph

Last Updated : 10 Jul, 2020
Bokeh is a Python interactive data visualization. It renders its plots using HTML and JavaScript. It targets modern web browsers for presentation providing elegant, concise construction of novel graphics with high-performance interactivity. Bokeh can be used to plot multiple patches on a graph. Plotting multiple patches on a graph can be done using the patches() method of the plotting module.

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
Example 1 : In this example we will be using the default values for plotting the graph. Python3 
# 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)
Output : Example 2 : In this example we will be plotting the patches with various other parameters Python3 
# 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)
