Creating a Scatter Chart with Multiple Lines in Excel

1. Open your Excel spreadsheet and select the data you want to use for your chart. Make sure you have all the data you need for each line in separate columns.
2. Click on the "Insert" tab in the top menu bar and select "Scatter" from the "Charts" section.
3. Choose the type of scatter chart you want to use. For multiple lines, you'll want to select the option that includes lines.
4. Once you've selected your chart type, Excel will create a basic chart for you. Right-click on the chart and select "Select Data" from the drop-down menu.
5. In the "Select Data Source" window, click on the "Add" button to add a new data series.
6. In the "Edit Series" window, enter a name for your new data series and select the data range for the X and Y values. Repeat this step for each line you want to add to your chart.
7. Once you've added all your data series, you can customize your chart by adding titles, labels, and adjusting the formatting to your liking.
8. Finally, save your chart and you're done!
