How to change ticks label sizes using Python’s Bokeh?

Bokeh is an interactive data plotting visualization library for modern web browsers. It provides elegant, concise construction of versatile graphics, and affords high-performance interactivity over large or streaming datasets.

In this article, we are going to discuss How to change ticks label sizes using Python’s Bokeh.

Step-by-step Approach:

• Now to plot any dataset using bokeh, the easiest way is to import the ‘figure’ and ‘show’ functions from the plotting class. The others are optional imports that help customize the graph.
• Create a figure object, that is going to plot the values from our provided dataset onto the graph.
• Now the ‘plot’ variable is going to be our figure object with a width of 700px and a height of 500px.
• Bokeh also gives us the ability to customize each axis.
• Assign or create a dataset. 
• No use label_text_font_size attribute decides the size of the tick label.
• Finally, depict the visualization.

Below are some examples based on the above approach:

Example 1:

Python3

from bokeh.plotting import figure, show
from bokeh.models import Legend

# Figure to plot
plot = figure(plot_width=700, plot_height=500)


# X axis customization
plot.xaxis.axis_label = "X Axis"
plot.xaxis.axis_label_text_color = "green"

# Y axis customization
plot.yaxis.axis_label = "Y Axis"
plot.yaxis.axis_label_text_color = "green"

# Creating the simple dataset
x = list(range(15))
y = [i**2 for i in x]

# setting the X and Y values
plot.line(x, y, line_width=4, line_color='lime',
          legend_label="label_text_font_size = '15pt'")

# Legend Customization
plot.legend.label_text_font_size = "15pt"
plot.legend.label_text_color = "green"

# Draw function
show(plot)

Output:

Example 2:

Python3

from bokeh.plotting import figure, show
from bokeh.models import Legend
from math import sin

# Figure to plot
plot = figure(plot_width=700, plot_height=500)


# X axis customization
plot.xaxis.axis_label = "X Axis"
plot.xaxis.axis_label_text_color = "green"

# Y axis customization
plot.yaxis.axis_label = "Y Axis"
plot.yaxis.axis_label_text_color = "green"

# Creating the simple dataset
x = y = list(range(10))


# setting the X and Y values
plot.line(x, y, line_width=4, line_color='lime',
          legend_label="label_text_font_size = '30pt'")

# Legend Customization
plot.legend.label_text_font_size = '30pt'
plot.legend.label_text_color = "green"

# Draw function
show(plot)

Output:
