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.
