The polynomial curvilinear trendline works well for large data sets with oscillating values that have more than one rise and fall. The formulas assume that you have 2 sets of variables: independent variable x and dependent variable y. In case of using polynomial equation you should follow the following formula in order to get the value of r2 because the point of r2 is located on (3,1) of matrix output. The Trendline is a bit similar to a line in a line chart, but it doesnât connect each data point precisely as a line chart does. A logarithmic trend is one in which the data rises or falls very quickly at the beginning but then slows down and levels off over time.
