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 quadrilaterals on a graph. Plotting quadrilaterals on a graph can be done using the quad()
method of the plotting
module.
plotting.figure.quad()
Syntax : quad(parameters)
Parameters :
- left : x-coordinates of the left edges of the quadrilateral
- right : x-coordinates of the right edges of the quadrilateral
- top : y-coordinates of top the edges of the quadrilateral
- bottom : y-coordinates bottom of the edges of the quadrilateral
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 Quadrilateral Graph" ,
match_aspect = True )
# the points to be plotted top = 3
bottom = 1
left = 0
right = 4
# plotting the graph graph.quad(left, right,
top,
bottom)
# displaying the model show(graph) |
Output :
Example 2 : In this example we will be plotting the multiple quadrilaterals 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 Quadrilateral 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 left = [ 2 , 3 , 6 ]
right = [ 1 , 5 , 0 ]
top = [ 3 , 6 , 6 ]
bottom = [ 1 , 5 , 2 ]
# color value of the patch color = [ "yellow" , "red" , "blue" ]
# fill alpha value of the patch fill_alpha = [ 0.9 , 0.7 , 0.5 ]
# plotting the graph graph.quad(left, right,
top,
bottom,
color = color,
fill_alpha = fill_alpha)
# displaying the model show(graph) |
Output :
