7 Steps To Create A Ternary Diagram In Excel

Creating a ternary diagram in Excel can seem daunting at first, but it’s a powerful way to visualize data that has three variables. Whether you’re analyzing compositions in chemistry, proportions in statistics, or any other tri-variable data, a ternary diagram can bring clarity to your data presentation. In this article, we’ll walk you through the seven steps to create a ternary diagram in Excel. By the end, you’ll be ready to use this tool effectively!

Understanding the Basics of Ternary Diagrams

A ternary diagram is a triangular graph that represents the proportions of three components that add up to a whole. Each corner of the triangle represents one of the three components, while any point within the triangle shows the relative proportions of each component.

Step 1: Organizing Your Data

To start, you’ll need to organize your data into three columns, representing the three variables you want to compare. Here’s an example:

Make sure that the sum of each row equals 100 to accurately represent percentages.

Step 2: Setting Up the Chart

1. Open Excel and highlight the data you’ve organized.
2. Go to the Insert tab.
3. Click on Scatter, and choose the “Scatter with Straight Lines” option. You won’t see the ternary diagram yet, but you’re laying the groundwork.

Step 3: Creating the Ternary Plot

1. Right-click on the chart area and select Select Data.
2. In the Select Data Source window, click Add.
3. You’ll need to plot the three components against each other. For this, you will have to do some calculations to convert your percentages to coordinates on the ternary diagram.

You can use the following formulas to get the coordinates for each data point:

• X-axis (Component A) = Component A / (Component A + Component B + Component C)
• Y-axis (Component B) = Component B / (Component A + Component B + Component C)

Step 4: Inputting Your Data into the Plot

After calculating your coordinates, return to the Select Data Source window:

1. Under Legend Entries (Series), you can create separate series for each data point you calculated.
2. Name them accordingly (like Data Point 1, Data Point 2, etc.).
3. Click OK to apply the data series.

Step 5: Formatting the Chart

Now you will want to format your chart to look more like a ternary diagram:

1. Click on the chart to select it.
2. Right-click and choose Format Data Series.
3. Adjust the series formatting: change the marker options, line colors, and thickness to your preference.

Step 6: Adding Ternary Axes

To make your chart more understandable, you’ll need to label the axes properly:

1. Click on the Chart Elements button (a plus icon next to the chart).
2. Check the boxes for Axis Titles and Data Labels.
3. Label each corner of the triangle to reflect your components (A, B, and C).

Step 7: Final Touches

Now that your ternary diagram is taking shape, add any final touches:

• Adjust the chart title to summarize your data representation.
• Consider changing the background color or grid lines to enhance visibility.
• Double-check data labels for clarity.

Important Note:

The data series in your ternary diagram should all be expressed in percentages. Make sure to keep your data consistent to maintain the accuracy of the diagram.
