Python Bokeh – Plotting Rays on a Graph Improve Improve Like Article Like Save Share Report 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 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 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 : Last Updated : 10 Jul, 2020 Like Article Save Article Previous Python Bokeh - Plotting Multiple Polygons on a Graph Next Python Bokeh - Plotting Multiple Patches on a Graph Share your thoughts in the comments Add Your Comment Please Login to comment...
