You can change the legend labels in this way: 1. The trendline is calculated Using the least squares method based on two data series. In line charts, column and bar graphs, numeric values are plotted only on the y-axis. Assuming the x range is B2:B13 and the y range is C2:C13, the real-life formulas go as follows: The same results can be achieved by using the LINEST function as an array formula.
