Python Bokeh – Plotting Line Segments 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 line segments on a graph. Plotting line segments on a graph can be done using the segment()
method of the plotting
module.
plotting.figure.segment()
Syntax : segment(parameters)
Parameters :
- x0 : x-coordinates of the starting points of the line segment
- y0 : y-coordinates of the starting points of the line segment
- x1 : x-coordinates of the ending points of the line segment
- y1 : y-coordinates of the ending points of the line segment
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 Segment Graph" )
x0 = 0
y0 = 0
x1 = 10
y1 = 10
graph.segment(x0, y0,
x1, y1)
show(graph)
|
Output :
Example 2 : In this example we will be plotting the multiple line segments with various other parameters
from bokeh.plotting import figure, output_file, show
output_file( "gfg.html" )
graph = figure(title = "Bokeh Segment Graph" )
graph.xaxis.axis_label = "x-axis"
graph.yaxis.axis_label = "y-axis"
x0 = [ 0 , 0 , 5 ]
y0 = [ 0 , 5 , 0 ]
x1 = [ 10 , 10 , 5 ]
y1 = [ 10 , 5 , 10 ]
line_color = [ "yellow" , "red" , "purple" ]
line_dash = "dotted"
line_width = [ 15 , 10 , 20 ]
graph.segment(x0, y0,
x1, y1,
line_color = line_color,
line_dash = line_dash,
line_width = line_width)
show(graph)
