Just wondering, When do you think the Statistical data annalisis tools, especially the regression line for the spreadsheet chart, will be done?
I have already work on some regression stuff, that you can find on issue 25478. The code already available on this issue can fit linear functions, exponential functions, logarithmic functions, potential functions and polynomial functions. It gives the computed functions, not only the curve. In fact, my code do not take care on the curve, because it is quite easy to draw a curve when you have got the functional to draw it.
"Regression line" sounds like linear regression, which Chart already does today. It just doesn't show the equation, but that's already on the list of feature wishes (http://graphics.openoffice.org/chart/featurewishes.html). Right now, the only way to see the parameters of the regression is to calculate them in spreadsheet cells (using the LINEST function for linear regression).
Regarding the original mail: There are some words you shouldn't use in mails, as otherwise overzealous spam filters might filter them out, together with all the spam you were talking about.
