2. Input Your Data:
   • Start a new worksheet or open an existing one.

   • | Month | Sales | Expenses ||-------|-------|----------|| Jan | 1000 | 800 || Feb | 1500 | 1200 |

Step 2: Select Your Data

2. Format Data Series:
   • Right-click on the highlighted data series and select Format Data Series from the context menu.
3. Move Series to Secondary Axis:

   • Check the Axis Titles box and choose Secondary Vertical.
2. Edit Axis Titles:

Step 6: Format the Chart for Clarity

1. Adjust Chart Style and Colors:
   • Click on the Chart Styles button next to the chart (a paintbrush icon).
   • Select a style that makes your data easily distinguishable.
2. Edit Data Labels (Optional):
   • Click on the data labels within the chart to highlight them.
   • Right-click and select Add Data Labels to view exact values on the chart.

Step 7: Final Adjustments
