How to Add a Trendline in Excel?


Excel trendline is a great way to visualize the general trend in your data. A trendline also called “a line of best fit,” is an analytical tool used to visualize and represent the behavior of a data set to see if there’s a pattern. With a trendline, you can gain deeper insight into your data at a glance, which makes them popular among investors, sales professionals, traders, and other professionals.

You can use them to get averages, notice peaks and drops to make better decisions, or even predict what’s coming. It is straightforward to create Trendlines for your data. Microsoft Excel has made inserting a trend line very easy, especially with the newer versions of Excel charts.

In Excel, most charts allow trendlines except for pie, radar, 3-D, stacked charts, and other similar ones.

As stated earlier, there are 6 different types of trendlines:

  1. Linear: From the name itself, this is a best-fit straight line usually used with simple linear data sets. Results are easy to interpret as they’re either increasing or decreasing at a steady rate.
  2. Logarithmic: This one is commonly used when quick changes in the data are leveling out. It’s a best-fit curved line and uses negative and positive values.
  3. Polynomial: A polynomial trendline is a curved line to visualize data fluctuations. The fluctuations are seen as a hill or valley in the trendline.
  4. Power: A power trendline is another curve line used with data sets comparing values that increase at a specific rate. This trendline is only possible for positive values.
  5. Exponential: An exponential trendline is also a curve valuable line for data sets with values that rise or fall at increasingly higher rates. You can’t use an exponential trendline with negative or zero values like a power trendline.
  6. Moving Average: This trendline is helpful in forecasting through moving averages. This shows a clear pattern or trend.
