Hi -
I'm tracking and charting real estate data in three cities, by month. I can
add updated info into the worksheet columns, but I can't get the
corresponding points into the line chart that I made three months ago from
the columns.

Now using excel 2007. Had no trouble with this task in excel 2003, becouse I
could easily change the data range and then the chart followed the changes.
I'm new in 2007, and when I find the data range and change it to correspond
the with the updated columns nothing happens in the chart

Appreciate help
