Creating a Sankey chart in Excel can visualize complex data flows and energy distribution patterns in a streamlined layout. Below is a step-by-step guide on how to craft a Sankey chart that brings your data to life with minimal hassle.
**Step 1: Arrange Your Data**
Ensure that your source data is properly organized in a table. Each column represents a segment of the Sankey diagram, and each cell value indicates the volume, strength, or size of the flow between segments. You will need at least four columns: from, to, value, and an optional label column.
**Step 2: Create the Basic Sankey Chart Structure**
Once your data is prepared, proceed to create a new workbook in Excel.
1. Enter your data in any sheet (usually the “Sheet1”).
2. Click on any cell within the data range to ensure your next action will apply to the table.
3. Navigate to the “Insert” tab in the Ribbon.
4. Here, choose the “Sankey” chart type, as one of the three options in the “Chart” section.
Excel will place your new Sankey chart on the worksheet.
**Step 3: Map the Data to Chart Elements**
1. In your Sankey chart, there are elements called “paths.” To map the elements to your data:
a. Right-click on the chart, select “Edit Data.”
b. Excel will open the “Edit Data” window showing a table link to your original data.
2. In the table link, double-click the first column “From,” then select your source data range (matching the “From” values).
3. Repeat this process for the “To” column, and then double-click the “Value” column to select the range of values that represent the data flows.
**Step 4: Customize the Path Width**
1. To customize the width of the flow paths, click and drag the line between the chart elements.
2. Hold down the Shift key to maintain equal width segments.
3. Dragging segments with the Shift key will vary the width of the path according to their value.
**Step 5: Adjust the Layout for Better Readability**
1. To improve the readability of your Sankey chart, go to the “Chart Tools”.
2. Choose the “Design” tab.
3. Look for the “Layouts” section and open the dropdown.
4. Pick a layout that aligns best with the structure of your Sankey diagram.
**Step 6: Add Legend and Improvements**
1. If your data requires a legend, add it to the chart:
a. Click the legend by clicking or dragging on it.
b. In the “Format Legend” pane that pops up, choose where you want the legend to appear within the chart area.
2. To fine-tune how the Sankey chart looks, you can use the “Format” contextual tab.
a. Once the element you want to format is selected, right-click and pick “Format Data Series.”
b. You can then modify fill, outline, and effects for the paths and nodes.
**Step 7: Final Touches**
After you have adjusted the layout, customization, and adjustments, preview your changes:
1. Before finalizing your Sankey chart, you may want to preview your updates:
a. You can do this by adjusting the font size in the chart. Larger text improves readability.
b. Add meaningful labels if your data permits it.
c. Arrange the chart on your worksheet for the best visual impact.
And that’s it! You now have a Sankey chart in Excel that visually represents the structure and quantities of the data you’ve provided. Sankey diagrams are great for illustrating the distribution of resources or energy efficiency and are now much more accessible thanks to Excel’s powerful graphing tools.
