The Excel Trend function will find the line of best fit for any set of values provided to it. Note that, it is not essential that the supplied points fit exactly along the straight line y = 2x + 10, (although they do in this example). The known x- and y-values are stored in cells A2-B5 of the spreadsheet, and are also shown in the spreadsheet graph.

In the spreadsheet below, the Excel Trend Function is used to extend a series of x- and y-values that lie on the straight line y = 2x + 10. Select the 'Options' tab and check 'Display Formula on Chart', then click OK. Trend Function Examples Example 1 - Extension of a Simple Straight Line To get that formula printed on the graph, put the cursor on the Trend Line and right-click.

Type your function into the first cell of the range, and press CTRL-SHIFT-Enter.See the Excel Array Formulas page for further details. To input an array formula, you need to first highlight the range of cells for the function result.

Therefore, the function must be entered as an Array Formula (see the examples below). If more than one new y-value is to be calculated by the Excel Trend function, the new values will be returned as an array. If is FALSE the constant b is set to 0 and the straight line equation becomes y = mx. If is TRUE (or if this argument is omitted) the constant b is treated normally ДЄn optional logical argument that specifes whether the constant 'b', in the straight-line equation y = mx + b, should be forced to be equal to zero.

ДЄn optional argument, providing one or more arrays of numeric values representing a set of new x-values, for which you want to calculate the corresponding new y-values.Д®ach array of should correspond to an array of. If omitted, the set of takes on the value. This is an optional argument which, if provided, should have the same length as the set of known_y's. Where the function arguments are as follows: known_y's
