Molly,
Actually, there is a way to make multiple charts on a single chart
sheet in Excel and one of the chart types would be with a Legend. The
others without a Legend.
To get the colors of all same data points to update to a new color,
you could do this with VBA or you could do it manually by changing the
color palette in Excel under Tools + Options + Colors.
And Glenna, don't be embarassed that you diidn't know how to do it. I
was flat out told by my 3 favorite programmers including someone who
concentrates primarily in Excel at a very very high level that this
could just not be done. Minutes later they had a sample in their
mailboxes.
The basic steps for creating multiple charts on a single chart sheet
are to create a chart on a chart sheet from a blank cell of data. You
won't see anything but the blank chart sheet.
Next create the actual charts and change the Location in the Chart
Wizard to point at that blank chart sheet as the location to put the
charts.
Now all you have to do is to size each chart object on the blank chart
sheet to meet your design requirements.
There are three other sources of information on this if you do a
little digging. Jon Peltier's web site, John Walkenbach's book on
charting in Excel. Jon also posted some sample VBA code in the Excel
Charting Newsgroup that can be modified to meet your needs if you know
any VBA. In any case it can be done and it can be done manually too.
