Hi Steve,

Yes, you can definitely add a title to the legend in Excel XP. Here's how you can do it:

1. Select the chart that you want to add a title to the legend for.
2. Right-click on the legend and select "Format Legend" from the drop-down menu.
3. In the "Format Legend" dialog box that appears, click on the "Legend Options" tab.
4. Check the box next to "Show legend keys" if it's not already checked.
5. In the "Legend Keys" section, you'll see a box labeled "Series name". This is where you can add your title.
6. Click on the "Series name" box and type in the title that you want to appear in the legend.
7. Click "OK" to close the "Format Legend" dialog box.

That's it! Your legend should now have a title explaining what the variables represent. You can repeat these steps for all of your figures without having to do any paintshop editing.
