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


Syntax : triangle(parameters)

Parameters :

  • x : x-coordinates of the center of the triangle markers
  • y : y-coordinates of the center of the triangle 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
# instantiating the figure object
graph = figure(title = "Bokeh Triangle Graph")
# the points to be plotted
x = 0
y = 0
# plotting the graph
graph.triangle(x, y, size = 30)
# displaying the model

Output :

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

# importing the modules 
from bokeh.plotting import figure, output_file, show 
# file to save the model 
# instantiating the figure object 
graph = figure(title = "Bokeh Triangle 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 triangles
color = ["yellow", "red", "purple"]
# fill alpha value of the triangles
fill_alpha = [0.9, 0.7, 0.5]
# plotting the graph 
graph.triangle(x, y,
               size = size,
               color = color,
               fill_alpha = fill_alpha) 
# displaying the model 

Output :
