# Working with TrendLines

## Content



The trend lines supported by chart with TrendLine objects can be divided into two groups, including regression and non-regression. In 2D charts, trend lines are typically used in X-Y line, bar, or scatter charts.

Non-regression trendlines are MovingAverage, Average, Minimum, and Maximum. Moving Average trendline is the average over the specified time.

Regression trend lines are **polynomial**, **exponent**, **logarithmic**, **power** and **Fourier functions** that approximate the data which the functions trend.
