Here, you can add titles, labels, and modify the colors and style of your chart. Customization helps make your chart more informative and visually appealing.

Step 5: Save and Share Your Chart

Finally, save your Excel file and share it as needed.

Make sure to save your work frequently to avoid losing any data. You can also export your chart as an image or PDF for easy sharing.

After completing these steps, you will have a clear and professional time series graph that effectively communicates your data trends over time.
