Change plotly Axis Labels in Python (Example)
Hi there! In this tutorial I will show you how to change the axis labels of your interactive plotly visualization in the Python programming language. It is simple and easy to do.
First, let us see what to expect in this article:
Now, let’s get started!
Install & Load the Python plotly Library
pip install plotly
This will install the plotly library along with all its dependencies. Next, you will need to load the library in your IDE using the following code:
import plotly.express as px
This will import the functions that can be used to create different visualizations in plotly, including the one we will use to create the scatterplot. Now, let’s create a scatterplot in plotly.
Create a Scatterplot
We are going to use the tips dataset that comes with the Python plotly library. In order to load the dataset, run the following line of code:
df = px.data.tips()
You can then print out the data frame to take a look like so:
total_bill tip sex smoker day time size 0 16.99 1.01 Female No Sun Dinner 2 1 10.34 1.66 Male No Sun Dinner 3 2 21.01 3.50 Male No Sun Dinner 3 3 23.68 3.31 Male No Sun Dinner 2 4 24.59 3.61 Female No Sun Dinner 4 .. ... ... ... ... ... ... ... 239 29.03 5.92 Male No Sat Dinner 3 240 27.18 2.00 Female Yes Sat Dinner 2 241 22.67 2.00 Male Yes Sat Dinner 2 242 17.82 1.75 Male No Sat Dinner 2 243 18.78 3.00 Female No Thur Dinner 2 [244 rows x 7 columns]
Now, we are going to create a scatterplot, where we will plot the “total_bill” column against the “tip” column, and color the points by the “sex” column. Run the code below to create the scatterplot:
fig = px.scatter(df,x = "total_bill",y = "tip",color = "sex") fig.show()
As you can see, “total_bill”, in the X axis, is plotted against “tip”, in the Y axis, and the plot is interactive, because you can hover over the plot to see the information in each data point, and to bring up other widgets that you can also interact with.
Change the Axis Labels of a plotly Plot
Now that we have created the scatterplot, let’s now see how to change the axis labels to whatever we want. In the code below, we shall change the X axis label “total_bill” to “Bill in dollars ($)” and the Y axis label “tip” to “Tip in dollars ($)”.
fig = px.scatter(df, x = "total_bill", y = "tip", color = "sex", labels = dict(total_bill = "Bill in dollars ($)",tip = "Tip in dollars ($)")) fig.show()
And that is how to change the axis labels of your plotly plot in Python. As you can see, it takes only a few lines of Python code to create an interactive scatterplot and to set its axis labels.
Thanks for reading, and I hope to see you in the next tutorial!
