You can get the formula of the linear regression easily using the SLOPE() and INTERCEPT() functions. Getting the formula actually printed on the graph ITSELF doesn't seem to be possible without perhaps doing some scripting. (Is there a way to easily assign the title or subtitle of a chart to be the value of a cell, like you can do in Excel? If that can be done, then the subtitle of the chart could be set to be the formula of the regression...) -- -------------------------------------------------------------------- * Charles Taylor <tomalek@xxxxxxxxxxxxxx> * Chemistry instructor / Mad scientist / Linux enthusiast! -------------------------------------------------------------------- * Web: http://home.mindspring.com/~charletiv/ --------------------------------------------------------------------
