Hi Dave,

To bring the smaller data set to the front in an area chart in Excel 2007, you can follow these steps:

1. Select the chart by clicking on it.
2. Click on the "Format" tab in the "Chart Tools" section of the ribbon.
3. In the "Current Selection" group, click on the drop-down menu and select the smaller data set that you want to bring to the front.
4. Right-click on the selected data set and choose "Format Data Series" from the context menu.
5. In the "Format Data Series" dialog box, click on the "Series Options" tab.
6. Under "Plot Series On", select "Primary Axis" if it is not already selected.
7. Under "Series Overlap", increase the value to move the smaller data set in front of the larger one. You can experiment with different values until you get the desired result.
8. Click "Close" to close the dialog box.

Your smaller data set should now be visible in front of the larger one in the area chart.
