When using a line graph, it is important to limit the number of data series to 1-3 primarily for clarity and ease of interpretation. Here are some reasons why using more than 3 series can be problematic:

  1. Clarity: A graph with too many lines can become cluttered and difficult to read. If there are many lines overlapping, it may be hard to discern which line represents which data series.

  2. Comparison: With 1-3 series, viewers can easily compare the trends and changes over time. More series can confuse the viewer and make it challenging to draw meaningful comparisons or insights.

  3. Visual Overload: The human eye can struggle to effectively track multiple lines, especially if they are similar in color or style. This can lead to misinterpretation of the data.

  4. Focus on Key Trends: Limiting the number of data series helps to focus on the key trends you want to highlight, making the graph more impactful.

In summary, while it is technically possible to plot more data series, keeping it to 1-3 series is recommended for better visualization and understanding.
