Python Bokeh – Plotting Triangles on a Graph
Last Updated :
10 Jul, 2020
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.
plotting.figure.triangle()
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.
from bokeh.plotting import figure, output_file, show
output_file("gfg.html")
graph = figure(title = "Bokeh Triangle Graph")
x = 0
y = 0
graph.triangle(x, y, size = 30)
show(graph)
|
Output :
Example 2 : In this example we will be plotting multiple triangles with various other parameters.
from bokeh.plotting import figure, output_file, show
output_file("gfg.html")
graph = figure(title = "Bokeh Triangle Graph")
graph.xaxis.axis_label = "x-axis"
graph.yaxis.axis_label = "y-axis"
x = [3, 3, 5]
y = [3, 1, 3]
size = [130, 100, 60]
color = ["yellow", "red", "purple"]
fill_alpha = [0.9, 0.7, 0.5]
graph.triangle(x, y,
size = size,
color = color,
fill_alpha = fill_alpha)
show(graph)
