How to plot multiple lines on the same y-axis using Plotly Express in Python

How to plot multiple lines on the same y-axis using Plotly Express in Python

Plotly Express is a high-level visualization library in Python that makes it easy to create interactive plots. To plot multiple lines on the same y-axis using Plotly Express, you can follow these steps:

  1. Import Required Libraries: First, import the necessary libraries: plotly.express for creating the plots and pandas to manage the data.

    import pandas as pd import plotly.express as px 
  2. Prepare Data: Create a pandas DataFrame with the data you want to plot. Each column should represent a line you want to plot.

    data = { 'x': [1, 2, 3, 4, 5], 'y1': [10, 15, 7, 12, 8], 'y2': [5, 9, 14, 7, 11] } df = pd.DataFrame(data) 
  3. Create the Plot: Use px.line() to create the line plot. Pass the DataFrame, specify the x-axis column, and use the y parameter to specify the columns you want to plot as lines.

    fig = px.line(df, x='x', y=['y1', 'y2']) 
  4. Customize the Plot: You can customize the plot appearance and add labels, titles, and other attributes.

    fig.update_layout( title='Multiple Lines Plot', xaxis_title='X-axis', yaxis_title='Y-axis', legend_title='Legend' ) 
  5. Show the Plot: Display the plot using fig.show().

    fig.show() 

Here's the complete code together:

import pandas as pd import plotly.express as px data = { 'x': [1, 2, 3, 4, 5], 'y1': [10, 15, 7, 12, 8], 'y2': [5, 9, 14, 7, 11] } df = pd.DataFrame(data) fig = px.line(df, x='x', y=['y1', 'y2']) fig.update_layout( title='Multiple Lines Plot', xaxis_title='X-axis', yaxis_title='Y-axis', legend_title='Legend' ) fig.show() 

This will create an interactive plot with two lines plotted on the same y-axis, labeled with their respective y-column names. You can further customize the plot based on your needs using Plotly Express's rich set of features.
