Python Bokeh – Plotting Triangle Pins on a Graph

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

plotting.figure.triangle_pin()

Syntax : triangle_pin(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
output_file("gfg.html")
         
# instantiating the figure object
graph = figure(title = "Bokeh Triangle Pin Graph")
       
# the points to be plotted
x = 0
y = 0
      
# plotting the graph
graph.triangle_pin(x, y, size = 30)
       
# displaying the model
show(graph)

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