Trendlines help you see an overall picture of data over time. They can even be used to forecast future trends and make predictions.
Choose a Trendline
Trendlines aren’t available with all types of charts. However, if you are using an area, bar, line, column, stock, scatter, or bubble chart that’s 2-dimentional, a trendline can be applied. There are six different types available. Use the table below to determine the right type of trendline for your chart and data.
|Chart Types in Excel|
|Exponential||Exponential trendlines work only for data sets with positive values. They’re best for data that increases or decreases at a quick rate.|
|Linear||Linear trendlines are best for simple sets of data where the data points are in a line that increase or decrease at a steady rate.|
|Logarithmic||If your data increases or decreases quickly and then evens out, a logarithmic trendline is the best to use. They are curved trendlines and can be used for charts with both positive and negative values.|
|Polynomial||Polynomial trendlines are curved lines for data with positive values. Use these if your data set fluctuates and you need to assess the ups and downs of a large set of data.|
|Power||Power trendlines are also curved lines for data with positive values. If your data increases at a specific rate, power trendlines are the best to use.|
|Moving Average||If your data has large fluctuations, a moving average trendline is best. They help neutralize variations to give you a better idea of the underlying trend.|
