A trend line that follows the overall pattern of the data points

Explanation:

Data point is the element that is represented by the combination of data obtained from your table and is the result of the correlation of the value in X and Y. When you need to make a trend line for a set of data points, it is advisable that this line follows the general pattern of data points. In this way it will be possible to create a data series that is composed of a table of values listed in columns or rows. Each column or row with values is called a series. In addition, it will be possible to establish data markers. Data markers are graphic elements used to represent data points.
