Ever found yourself in a pickle trying to extend a trendline in Excel 2016? It’s actually not as hard as you might think. All you need to do is click on the trendline, then drag the handle to the desired length. Voila! You’ve extended your trendline.
Step by Step Tutorial: Extending a Trendline in Excel 2016
Before we dive into the steps, let’s talk about why you might want to extend a trendline. Extending a trendline can help you predict future data points based on the current trend. It’s a nifty little trick that can give you insights into where things might be heading.
Step 1: Select the Chart
Click on the chart that contains the trendline you want to extend.
Selecting the chart is crucial because it allows you to edit the elements within it, including the trendline.
Step 2: Click on the Trendline
Once the chart is selected, click directly on the trendline.
You might need to click a few times to select the trendline itself rather than the data points.
Step 3: Drag the Handle
After selecting the trendline, drag the square handle at either end to extend it.
Be careful not to click on the resize handles of the chart itself, as this will resize the chart instead of extending the trendline.
Once you’ve extended the trendline, you’ll be able to see the projected data points based on the existing trend.
