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 wedges on a graph. Plotting wedges on a graph can be done using the wedge() method of the plotting module.
plotting.figure.wedge()
Syntax : wedge(parameters)
Parameters :
- x : x-coordinates of the wedge markers
- y : y-coordinates of the wedge markers
- radius : radius of the wedge markers
- radius_units : unit of the radius of the wedge markers, default is radian
- start_angle : angle to start the wedge markers
- start_angle_units : unit of the angle to start the wedge markers, default is radian
- end_angle : angle to end the wedge markers
- end_angle_units : unit of the angle to end the wedge markers
- direction : direction of strokes, default is anticlock
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 Wedge Graph") # the points to be plotted x = 0y = 0 # radius of the wedge radius = 15 # start angle of the wedge start_angle = 1 # end angle of the wedge end_angle = 2 # plotting the graph graph.wedge(x, y, radius = radius, start_angle = start_angle, end_angle = end_angle) # displaying the model show(graph) |
Output :
Example 2 : In this example we will be plotting multiple wedges 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 Wedge 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, 5, 0] y = [0, 5, 5] # radius of the wedges radius = [15, 10, 5] # start angle of the wedges start_angle = [1, 2, 3] # end angle of the wedges end_angle = [2, 4, 6] # color value of the wedges color = ["yellow", "red", "purple"] # fill alpha value of the wedges fill_alpha = [0.9, 0.7, 0.5] # plotting the graph graph.wedge(x, y, radius = radius, start_angle = start_angle, end_angle = end_angle, color = color, fill_alpha = fill_alpha) # displaying the model show(graph) |
