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 rays on a graph. Plotting rays on a graph can be done using the ray()
method of the plotting
module.
plotting.figure.ray()
Syntax : ray(parameters)
Parameters :
- x : x-coordinates of the starting points of the rays
- y : y-coordinates of the starting points of the rays
- length : length of the ray
- length_units : unit of the length of the rays
Returns : an object of class

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 Rays Graph" )
# the points to be plotted x = 0
y = 0
# plotting the graph graph.ray(x, y) # displaying the model show(graph) |
Output :
Example 2 : In this example we will be plotting multiple rays with various other parameters.
# importing the modules from bokeh.plotting import figure, output_file, show
from bokeh.palettes import magma
import numpy
# file to save the model output_file( "gfg.html" )
# instantiating the figure object graph = figure(title = "Bokeh Rays 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 = [ 0 ] * 256
y = [ 0 ] * 256
# angles of the rays angle = numpy.linspace( 0.00 , 6.28 , num = 256 ).tolist()
# color of the rays color = magma( 256 )
# plotting the graph graph.ray(x, y, angle = angle,
color = color)
# displaying the model show(graph) |
Output :
