Hi,
Trend lines are based on all the data points in a series. To get a trend line on a subset of data you will need to add a new series based on only that subset.

Hi,
If you want the chart to do this, then one way is to plot the "obvious linear protion" as one series and the rest as another series and then select the above portion and choose Chart, Add Trendline. You could also manually calculate the trendline in the spreadsheet for the points that make up the "obvious linear portion" using some combination of the LINEST, TREND, SLOPE or INTERCEPT spreadsheet functions. Then you would calculate and plot the trendline as a separate series. I suspect you can find at least one example at Jon's website. Google Excel Charts and look for Jon Peltier's sites. -- Thanks, Shane Devenshire "mechengstudent" wrote: I want a best fit line to go pass through the obviously linear portion of the data and ignore all other points, how do i do this? |
