How to Utilize Goal Seek in Microsoft Excel
A bubble chart is an enhanced scatter plot that displays three data series (X, Y, and Z values). The size of the bubbles represents the third variable, making it great for financial data, market analysis, or any dataset where size matters.
📌 Organizing Your Data for a Bubble Chart
Before creating a bubble chart, ensure your data is structured correctly:
✅ X-values (e.g., Quantity) in the first column.
✅ Y-values (e.g., Cost) in the second column.
✅ Z-values (e.g., Sales) in the third column (bubble size).
✅ Include at least four rows or columns of data.
✅ Do not include headers when selecting data for the chart.
Example Data Table
| Quantity (X) | Cost (Y) | Sales (Z – Bubble Size) |
|---|---|---|
| 10 | 500 | 300 |
| 15 | 700 | 450 |
| 20 | 850 | 600 |
| 25 | 1000 | 750 |
