One way to assess this fluctuating data is to add a linear trend line to the Excel 2013 graph. This visual element considers all the data and displays the overall direction the values are taking.

To do this, begin by writing your equation. For example: y=x+3 or y=sin(x)+cos(2x). Next, use Lasso tool to select the equation and then, on the Draw tab, click the Math button.. Now, from the ...
