Python Bokeh Plotting a Scatter Plot on a Graph (original) (raw)

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 a scatter plot on a graph. Plotting squares on a graph can be done using the scatter() method of the plotting module.

plotting.figure.scatter()

Syntax : scatter(parameters)Parameters :

• x : x-coordinates of the center of the glyphs
• y : y-coordinates of the center of the glyphs
• marker : signifies the type of the glyph Returns : an object of class GlyphRenderer

Example 1 : In this example we will be using the default values for plotting the graph.

Python3 `

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 Scatter Graph")

the points to be plotted

x = [1, 2, 3, 4, 5] y = [1, 2, 3, 4, 5]

plotting the graph

graph.scatter(x, y)

displaying the model

show(graph)

`

Output : Example 2 : In this example we will be plotting multiple scatter points with various other parameters

Python3 `

importing the modules

from bokeh.plotting import figure, output_file, show from bokeh.palettes import magma import random

file to save the model

output_file("gfg.html")

instantiating the figure object

graph = figure(title = "Bokeh Scatter 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 = [n for n in range(256)] y = [random.random() + 1 for n in range(256)] size = 10

color value of the scatter points

color = magma(256)

plotting the graph

graph.scatter(x, y, size = size, color = color)

displaying the model

show(graph)

`

Output :
