FYI, in Excel 2007, I get the same values for RSQ and displayed as r2 on the chart (0.921914019817796) I plotted an x-y scatter chart, linear trendline. Select the first value of the new trendline and copy the function by using Excel's Auto Fill feature, dragging theįill handle in the cell's lower right corner to the right until the cell of the last value is selected as well. This way the selection will stay exactly the same when this formula isĬopied and will not be adjusted according to the new position. Of the selected cells will change to absolute cell references. Select the first x value (e.g., "B1") and press ENTER. Select all "known x" values and press F4 (e.g., "$B$1:$D$1").
