Python Bokeh – Plotting Xs on a Graph

0 0 2 minutes read

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 Xs on a graph. Plotting Xs on a graph can be done using the x() method of the plotting module.

plotting.figure.x()

Syntax : x(parameters)

Parameters :

x : x-coordinates of the center of the x markers

y : y-coordinates of the center of the x markers

Returns : an object of class GlyphRenderer

Example 1 : In this example we will be using the default values for plotting the graph.

# 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 X Graph") 
       
# the points to be plotted 
x = 0
y = 0
      
# plotting the graph 
graph.x(x, y, size = 30) 
       
# displaying the model 
show(graph) 

Output :

Example 2 : In this example we will be plotting multiple Xs with various other parameters.

# 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 X 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 = [3, 3, 5] 
y = [3, 1, 3] 
size = [130, 100, 60] 
   
# color value of the Xs 
color = ["yellow", "red", "purple"] 
   
# fill alpha value of the Xs 
fill_alpha = [0.9, 0.7, 0.5] 
  
# line width of the Xs 
line_width = [10, 15, 5] 
  
# plotting the graph  
graph.x(x, y, 
        size = size, 
        color = color, 
        fill_alpha = fill_alpha, 
        line_width = line_width)  
        
# displaying the model  
show(graph)
