**Trend Line**

*Trend Line* is a line indicating the general course or tendency of points on your chart.

**Regression Type**

Choose the representation type of the trend line:

__Linear__

A linear trendline is a best-fit straight line that is used with simple linear data sets.

__Power__

A power trendline is a curved line that is best used with data sets that compare measurements that increase at a specific rate.

__Exponential__

An exponential trendline is a curved line that is most useful when data values rise or fall at increasingly higher rates. You cannot create an exponential trendline if your data contains zero or negative values.

__Logarithmic__

A logarithmic trendline is a best-fit curved line that is most useful when the rate of change in the data increases or decreases quickly and then levels out. A logarithmic trendline can use negative and/or positive values.

__Polynomial__
