How To Make a Percent Finer Graph in Excel

Creating a percent finer graph in Excel, often used in particle size analysis or sieve analysis, allows for a clear visualization of the cumulative percentage of particles finer than a given size. This guide provides a step-by-step approach to crafting this insightful graph. We'll cover data preparation, chart creation, and formatting for optimal readability and impact.

Preparing Your Data for the Graph

Before diving into Excel, ensure your data is organized correctly. You'll need two columns:

• Column 1: Particle Size (Sieve Size): List your sieve sizes in descending order (largest to smallest). Ensure consistent units (e.g., micrometers, millimeters).
• Column 2: Cumulative Percent Finer: This column represents the percentage of particles that passed through each sieve. This is your cumulative percentage, meaning the percentage at each sieve size includes all particles that passed through that sieve and all smaller sieves.

Example Data:

Creating the Percent Finer Graph in Excel

1. Select your data: Highlight both columns containing your particle size and cumulative percent finer data.

2. Insert a Scatter Chart: Go to the "Insert" tab and choose the "Scatter" chart type. Select the option that shows data points without lines connecting them (a simple scatter plot). This is crucial for accurately representing a percent finer graph.

3. Title and Axis Labels: Add a clear and concise title to your chart (e.g., "Particle Size Distribution - Percent Finer"). Label your axes appropriately: "Particle Size (µm)" for the horizontal (X) axis and "Cumulative Percent Finer" for the vertical (Y) axis. Clearly state the units.

4. Formatting for Clarity:

   • Data Points: Consider adding data labels to your points to show the exact cumulative percentage at each size. Right-click on a data point, select "Add Data Labels," and choose a suitable position for the labels.
   • Axis Scaling: Ensure the Y-axis scales from 0% to 100%. The X-axis should reflect the full range of your particle sizes.
   • Gridlines: Adding major and minor gridlines can improve readability, particularly for detailed analysis.
   • Chart Style: Choose a chart style that complements your overall presentation. Keep it clean and professional.

Optimizing Your Graph for SEO and Readability

• Keyword Optimization: Use relevant keywords in your chart title, axis labels, and any accompanying text. Keywords like "percent finer," "particle size distribution," "sieve analysis," and "cumulative percentage" will be beneficial.
• Image Alt Text: If embedding this graph into a website or blog, ensure you add descriptive alt text to the image. This helps screen readers and search engines understand the content of the chart. A good alt text might be: "Particle Size Distribution Graph showing cumulative percent finer for a sample, with sieve sizes ranging from 1000 µm to 0 µm."
• Context and Explanation: Don't just present the graph; provide context. Explain what the graph represents, what the data means, and any key findings or insights. This enhances readability and provides valuable information for your audience.

Beyond the Basics: Advanced Techniques

• Logarithmic Scale: For a wider range of particle sizes, consider using a logarithmic scale for the X-axis (Particle Size). This allows for better visualization of data spanning several orders of magnitude. This can be adjusted within the chart formatting options.
• Multiple Datasets: You can add multiple datasets to compare different samples or treatments on the same graph, making it a powerful tool for comparative analysis.
• Trendline: While less common in strict percent finer analysis, a trendline (e.g., a curve fit) might be appropriate to visually highlight the overall distribution trend if warranted by the data.

By following these steps, you can create a clear, informative, and search-engine-friendly percent finer graph in Excel. Remember that a well-presented graph enhances comprehension and makes your analysis more impactful.
