Format Title of plotly Graph in Python (Example)

Hello folks! Welcome again to another educative tutorial. In this tutorial, you’ll learn how to format the title of your plotly graph in the Python programming language. As with other aspects of building or modifying a plotly graph in Python, it is very simple and easy to format the title of a graph, as we shall soon see.

But first, let us see what steps are involved in building a plotly graph in Python and then formatting its title:

Now that we have seen the steps we shall take to achieve our goal, let’s get into it!
 

Install Python plotly Library

Before we can build graphs in plotly, we need to first install the library. To install the plotly library in Python, you can run the code below in your preferred Python IDE:

pip install plotly

This will install plotly and all its dependencies in your Python environment, making it ready for use in your projects.
 

Load Python plotly Library

Now that we have installed the Python plotly library, we shall now load it so that we can have access to its plot-building functions, including the one we shall use in this tutorial. To load plotly, please run the code below:

import plotly.express as px

Build A Barplot

Now that we have installed and loaded the Python plotly library, let us now build a simple barplot. Please run the lines of code below to build a simple barplot:

fig = px.bar(x = ["A","B","C","E","F"],
             y = [2,3,4,5,6],
             title = "A Simple Bar Plot")
fig.show()

Format Barplot Title

Great! We have just built a barplot with a plot title in Python with plotly. Now, let us customize the plot title. We are going to change the font family to “Sitka Small” and set the font color to green using the fig.update_layout() function. You can play around with different font styles and color. Please run the code below to see how our plot title has been formatted:

fig = px.bar(x = ["A","B","C","E","F"],
             y = [2,3,4,5,6],
             title = "A Simple Bar Plot")
fig.update_layout(
    title_font_family="Sitka Small",
    title_font_color="green")
fig.show()

Awesome! There you have it, we have just formatted the plot title of our plotly barplot. As promised, it turned out to be very simple and easy to do. With the fig.update_layout() function, you can actually add some more customizations to your plot and make it look the way you want.

I hope you learned something new and valuable in this tutorial, and I will see you in the next one. Take care!
