Bokeh - Setting Ranges

Numeric ranges of data axes of a plot are automatically set by Bokeh taking into consideration the dataset under process. However, sometimes you may want to define the range of values on x and y axis explicitly. This is done by assigning x_range and y_range properties to a figure() function.

These ranges are defined with the help of range1d() function.

Example

xrange = Range1d(0,10)

To use this range object as x_range property, use the below code −

fig = figure(x,y,x_range = xrange)

Example - Usage of Range1d

main.py

from bokeh.plotting import figure, output_file, show
import numpy as np
import math
from bokeh.models import Range1d

x = np.arange(0, math.pi*2, 0.05)
y = np.sin(x)

output_file("sine.html")

xrange = Range1d(0,10)
fig = figure(width = 300, height = 300, x_range = xrange)
fig.line(x, y, legend_label = "sine", line_width = 2)

show(fig)
