Following, select the range of cells for the Years and click OK.Next, a dialog box appears where we can change the Axis Labels to show Years.Secondly, select the chart and right-click on the mouse.Now, choose the 2D Line Chart as shown in the image below.Next, navigate to the Insert > Line Chart drop-down.Firstly, insert 3 new rows in the Year column.So, without further delay, let’s see the process bit-by-bit. Luckily, Excel allows us to extrapolate trendlines using charts.
If const is FALSE, b is set equal to 0 (zero), and the m-values are adjusted so that y = mx.Here, D5 and D6 cells refer to the Sales amount of $1246 and $1783, respectively, whereas the C5 and C6 cells indicate the Month numbers 1 and 2.įinally, use copying the formula to the next cell to obtain the results for April.Ĥ Methods to Extrapolate Trendline in ExcelĬonsidering the dataset in the B4:C9 cells, which contains the US Population data for each decade starting from the Year 1950.ġ. If const is TRUE or omitted, b is calculated normally. If known_x's is omitted, it is assumed to be the array that is the same size as known_y's.Ī logical value specifying whether to force the constant b to equal 0 If more than one variable is used, known_y's must be a vector (that is, a range with a height of one row or a width of one column). If only one variable is used, known_y's and known_x's can be ranges of any shape, as long as they have equal dimensions. The array known_x's can include one or more sets of variables. If the array known_y's is in a single row, then each row of known_x's is interpreted as a separate variable.Īn optional set of x-values that you may already know in the relationship y = mx + b If the array known_y's is in a single column, then each column of known_x's is interpreted as a separate variable.
The set of y-values you already know in the relationship y = mx + b The TREND function syntax has the following arguments:
