Subject: Using Excel 2007 My Excel examples were done using Excel 2003. Some students have said they've had problems using Excel 2007, especially trying to get more than one plot (set of data) on the same graph. Things are actually very similar to my example. Here are a few things that may help: 1) To make a graph you highlight your x and y data. Then go up to "Insert". There you will see "Charts". This will insert a chart in the workspace. When you do this you will see something called "Chart Tools" appear above the "Design" tab. Click on this. You will then get many different functions for charts. 2) How to get more than one set of data on the same graph? There are several ways of doing this. a) In my example, (done with Excel 2003 on an XP machine) the easiest thing is to right click in the graph area and choose "Source Data" in the pop-up window. In Excel 2007 you essentially do the same thing except choose "Select Data". From there it's pretty much what my example shows. b) In Excel 2007 you can also do this by clicking in the graph area and then clicking on "Chart Tools" (above the "Design" tab). Several new options appear, one of which is "Select Data". 3) You will also find many other things in "Chart Tools", such as "Move Chart", which allows you to move the chart to a new tab (out of the current workspace). I recommend this. 4) Right clicking on the outside edge of the chart itself will bring up a pop-up window with lots of options as well. 5) If you ever want to send me your Excel file from Excel 2007 you will need to save it as an Excel 2003 (xls) file or I won't be able to look at it. I guess this brings up something else. Be inquisitive. When searching for things just start clicking. If you've saved your file you won't lose any information or mess anything up. Using the right mouse button is a useful tool, especially in a chart. The first time I used Excel 2007 (after the initial shock of how it looked) it took me about 10-15 minutes to make up some data, make a chart, find "Select Data", put the chart in a new window and do the trendline. Of course I already knew how to use Excel 2003. Finally, don't wait until the last minute. If you e-mail me for help at 2 AM I may see it, but don't count on it. Even if I do see it, there may not be enough time for you to make fixes. Dr. Zellmer
