The ‘step’ function present in glyph function is used to generate discrete data points.
Example
from bokeh.plotting import figure, output_file, show
output_file("stepLine.html")
p = figure(plot_width=500, plot_height=300)
p.step([2, 5, 3, 6, 7,9], [6,3, 2, 1, 0, 5], line_width=2, mode="center")
show(p)Output
Explanation
The required packages are imported, and aliased.
The figure function is called along with plot width and height.
The ‘output_file’ function is called to mention the name of the html file that will be generated.
The ‘step’ function present in Bokeh is called, along with data.
It helps render the steps.
The ‘show’ function is used to display the plot.
