Re: Dynamic trend line
|
|
The chart contains 2 data
series. One is linked to the data and therefore maintains the
correct number of categories. The other data series uses a
Named Range as its data source.
The Trendline is plotted against the second data series and
will update when new data is added. This approach allows you
to use all of the trend line types and their formatting options.
Named range
ChartData =OFFSET(Sheet1!$A$2,0,1,COUNT(Sheet1!$B:$B),1)
This
workbook contains an example.
