Adjusting Trendlines in a Chart

Patricio noted that in earlier versions of Excel (Excel 2003) when working with a line chart he could grab the trendline and move it up or down. Doing so would cause the data associated with the line to change accordingly. He found this functionality helpful for evaluating trends and forecasting. In Excel 2007 and Excel 2010 the actual data table has to be modified; Patricio hasn't found a way to move the trendline in the chart itself. He wonders if the feature has been removed from Excel or if there is there some setting he needs to configure in the program.

Patricio is correct; this capability was removed from Excel 2007 and not put into Excel 2010. (In the words of Microsoft folk, the feature was "deprecated.") There is some talk about it being placed back into future versions of Excel, but only time will tell if that happens.

One thing that you might be interested in is a free Excel add-in that provides some of the capabilities of the removed feature. You can read more about it at Microsoft's Office blog, here:

I never got to use this feature but can see how useful it would be for forecasting. If not already mentioned in the Microsoft blog (which I can't take the time to read now) it would be icing on the cake for this functionality to turn the changed data red or similar color so analysts can clearly see what their moved trend line affects directly. Other useful improvements would be a Return To Actual Data button and the ability to "ghost" the moved trendline while the real one remains in place; perhaps the ghosted, moved trendline's data could appear in a tear-off window next to the real data too. The point is to give analysts the most convenient visual cues to help them find patterns and solutions. Thanks for posting this interesting information.

Was this fixed for Excel 2013? I am working with data and would like grab lines and adjust them on the y-axis to see trends but have not found a way to do so.

I have great difficulty in relocating and placing the cursor on a previously made trendline. Is there some trick to finding the trend line to reformat it?

To be honest, I'm not surprised this is deprecated. It sounded dodgy as soon as I heard about it (ie last week).

Yes, useful for modellers and "what-if" - but dangerous for those on the reporting side of the show.
